"Proprietary software is software that comes with restrictions that retain control of how software can be used, shared, and changed through the use of copyright and licensing."
"If a technology is exclusionary, it does not work. If a community is exclusionary, it must be fixed or thrown away. There is no middle ground here. There is no compromise. Without doing this, without taking the hard, painful steps to actually live the promise of user freedom and everything it requires and entails, our work is pointless and free software will fail."
"Well we can use our collective power to push others"
"What they had in common was mainly love of excellence and programming. They wanted to make their programs that they used be as good as they could. They also wanted to make them do neat things. They wanted to be able to do something in a more exciting way than anyone believed possible and show "Look how wonderful this is. I bet you didn't believe this could be done.""
"I consider that the golden rule requires that if I like a program I must share it with other people who like it. Software sellers want to divide the users and conquer them, making each user agree not to share with others. I refuse to break solidarity with other users in this way. I cannot in good conscience sign a nondisclosure agreement or a software license agreement. For years I worked within the Artificial Intelligence Lab to resist such tendencies and other inhospitalities, but eventually they had gone too far: I could not remain in an institution where such things are done for me against my will. So that I can continue to use computers without dishonor, I have decided to put together a sufficient body of free software so that I will be able to get along without any software that is not free. I have resigned from the AI lab to deny MIT any legal excuse to prevent me from giving GNU away."
"GNU is not in the public domain. Everyone will be permitted to modify and redistribute GNU, but no distributor will be allowed to restrict its further redistribution. That is to say, proprietary modifications will not be allowed. I want to make sure that all versions of GNU remain free."
"To avoid horrible confusion, please pronounce the G in the word GNU when it is the name of this project."
"Arrangements to make people pay for using a program, including licensing of copies, always incur a tremendous cost to society through the cumbersome mechanisms necessary to figure out how much (that is, which programs) a person must pay for. And only a police state can force everyone to obey them. Consider a space station where air must be manufactured at great cost: charging each breather per liter of air may be fair, but wearing the metered gas mask all day and all night is intolerable even if everyone can afford to pay the air bill. And the TV cameras everywhere to see if you ever take the mask off are outrageous. It's better to support the air plant with a head tax and chuck the masks. Copying all or parts of a program is as natural to a programmer as breathing, and as productive. It ought to be as free."
"It may be true that one can reach more microcomputer users with advertising. If this is really so, a business which advertises the service of copying and mailing GNU for a fee ought to be successful enough to pay for its advertising and more. This way, only the users who benefit from the advertising pay for it. On the other hand, if many people get GNU from their friends, and such companies don't succeed, this will show that advertising was not really necessary to spread GNU. Why is it that free market advocates don't want to let the free market decide this?"
"If anything deserves a reward, it is social contribution. Creativity can be a social contribution, but only in so far as society is free to use the results. If programmers deserve to be rewarded for creating innovative programs, by the same token they deserve to be punished if they restrict the use of these programs."
"There is nothing wrong with wanting pay for work, or seeking to maximize one's income, as long as one does not use means that are destructive. But the means customary in the field of software today are based on destruction."
"Extracting money from users of a program by restricting their use of it is destructive because the restrictions reduce the amount and the ways that the program can be used. This reduces the amount of wealth that humanity derives from the program. When there is a deliberate choice to restrict, the harmful consequences are deliberate destruction. The reason a good citizen does not use such destructive means to become wealthier is that, if everyone did so, we would all become poorer from the mutual destructiveness. This is Kantian ethics; or, the Golden Rule. Since I do not like the consequences that result if everyone hoards information, I am required to consider it wrong for one to do so. Specifically, the desire to be rewarded for one's creativity does not justify depriving the world in general of all or part of that creativity."
"Restricting copying is not the only basis for business in software. It is the most common basis because it brings in the most money. If it were prohibited, or rejected by the customer, software business would move to other bases of organization which are now used less often. There are always numerous ways to organize any kind of business."
"Control over the use of one's ideas really constitutes control over other people's lives; and it is usually used to make their lives more difficult."
"The idea of copyright did not exist in ancient times, when authors frequently copied other authors at length in works of non-fiction. This practice was useful, and is the only way many authors' works have survived even in part. The copyright system was created expressly for the purpose of encouraging authorship. In the domain for which it was invented — books, which could be copied economically only on a printing press — it did little harm, and did not obstruct most of the individuals who read the books."
"Every decision a person makes stems from the person's values and goals. People can have many different goals and values; fame, profit, love, survival, fun, and freedom, are just some of the goals that a good person might have. When the goal is to help others as well as oneself, we call that idealism. My work on free software is motivated by an idealistic goal: spreading freedom and cooperation. I want to encourage free software to spread, replacing proprietary software that forbids cooperation, and thus make our society better."
"All intellectual property rights are just licenses granted by society because it was thought, rightly or wrongly, that society as a whole would benefit by granting them. But in any particular situation, we have to ask: are we really better off granting such license? What kind of act are we licensing a person to do?"
"The case of programs today is very different from that of books a hundred years ago. The fact that the easiest way to copy a program is from one neighbor to another, the fact that a program has both source code and object code which are distinct, and the fact that a program is used rather than read and enjoyed, combine to create a situation in which a person who enforces a copyright is harming society as a whole both materially and spiritually; in which a person should not do so regardless of whether the law enables him to."
"The paradigm of competition is a race: by rewarding the winner, we encourage everyone to run faster. When capitalism really works this way, it does a good job; but its defenders are wrong in assuming it always works this way. If the runners forget why the reward is offered and become intent on winning, no matter how, they may find other strategies — such as, attacking other runners. If the runners get into a fist fight, they will all finish late. Proprietary and secret software is the moral equivalent of runners in a fist fight."
"People with new ideas could distribute programs as freeware, asking for donations from satisfied users, or selling hand-holding services. I have met people who are already working this way successfully."
"We have already greatly reduced the amount of work that the whole society must do for its actual productivity, but only a little of this has translated itself into leisure for workers because much nonproductive activity is required to accompany productive activity. The main causes of this are bureaucracy and isometric struggles against competition. Free software will greatly reduce these drains in the area of software production. We must do this, in order for technical gains in productivity to translate into less work for us."
"I have met bright students in computer science who have never seen the source code of a large program. They may be good at writing small programs, but they can't begin to learn the different skills of writing large ones if they can't see how others have done it. In any intellectual field, one can reach greater heights by standing on the shoulders of others. But that is no longer generally allowed in the software field—you can only stand on the shoulders of the other people in your own company."
"Hundreds of thousands of babies are born every day. While the whole phenomenon is menacing, one of them by itself is not newsworthy. Nor is it a difficult achievement — even some fish can do it. (Now, if you were a seahorse, it would be more interesting, since it would be the male that gave birth.) ...These birth announcements also spread the myth that having a baby is something to be proud of, which fuels natalist pressure, which leads to pollution, extinction of wildlife, poverty, and ultimately mass starvation."
"In 1971 when I joined the staff of the MIT Artificial Intelligence lab, all of us who helped develop the operating system software, we called ourselves hackers. We were not breaking any laws, at least not in doing the hacking we were paid to do. We were developing software and we were having fun. Hacking refers to the spirit of fun in which we were developing software. The hacker ethic refers to the feelings of right and wrong, to the ethical ideas this community of people had — that knowledge should be shared with other people who can benefit from it, and that important resources should be utilized rather than wasted. Back in those days computers were quite scarce, and one thing about our computer was it would execute about a third-of-a-million instructions every second, and it would do so whether there was any need to do so or not. If no one used these instructions, they would be wasted. So to have an administrator say, "well you people can use a computer and all the rest of you can't," means that if none of those officially authorized people wanted to use the machine that second, it would go to waste. For many hours every morning it would mostly go to waste. So we decided that was a shame. Anyone should be able to use it who could make use of it, rather than just throwing it away. In general we did not tolerate bureaucratic obstructionism. We felt, "this computer is here, it was bought by the public, it is here to advance human knowledge and do whatever is constructive and useful." So we felt it was better to let anyone at all use it — to learn about programming, or do any other kind of work other than commercial activity."
"People could no longer learn hacking the way I did, by starting to work on a real operating system, making real improvements. In fact, in the 1980s I often came across newly graduated computer science majors who had never seen a real program in their lives. They had only seen toy exercises, school exercises, because every real program was a trade secret. They never had the experience of writing features for users to really use, and fixing the bugs that real users came across. The things you need to know to do real work."
"A hacker is someone who enjoys playful cleverness — not necessarily with computers. The programmers in the old MIT free software community of the 60s and 70s referred to themselves as hackers. Around 1980, journalists who discovered the hacker community mistakenly took the term to mean “security breaker.”"
"Publishers and lawyers like to describe copyright as “intellectual property” — a term also applied to patents, trademarks, and other more obscure areas of law. These laws have so little in common, and differ so much, that it is ill-advised to generalize about them. It is best to talk specifically about “copyright,” or about “patents,” or about “trademarks.” The term “intellectual property” carries a hidden assumption—that the way to think about all these disparate issues is based on an analogy with physical objects, and our conception of them as physical property. When it comes to copying, this analogy disregards the crucial difference between material objects and information: information can be copied and shared almost effortlessly, while material objects can't be. To avoid spreading unnecessary bias and confusion, it is best to adopt a firm policy not to speak or even think in terms of “intellectual property”. The hypocrisy of calling these powers “rights” is starting to make the World “Intellectual Property” Organization embarrassed."
"Writing non-free software is not an ethically legitimate activity, so if people who do this run into trouble, that's good! All businesses based on non-free software ought to fail, and the sooner the better."
"The use of “hacker” to mean “security breaker” is a confusion on the part of the mass media. We hackers refuse to recognize that meaning, and continue using the word to mean someone who loves to program, someone who enjoys playful cleverness, or the combination of the two."
"If we are content with knowledge as a commodity, accessible only through a computerized bureaucracy, we can simply let companies provide it. But if we want to keep human knowledge open and freely available to humanity, we have to do the work to make it available that way. We have to write a free encyclopedia."
"Very ironic things have happened, but nothing to match this — giving the Linus Torvalds Award to the Free Software Foundation is sort of like giving the Han Solo Award to the Rebel Fleet."
"The patent system was established to encourage inventors to disclose the details of their inventions. Its purpose was to help society rather than to help inventors. At the time, the life span of 17 years for a patent was short compared with the rate of advance of the state of the art. Since patents are an issue only among manufacturers, for whom the cost and effort of a license agreement are small compared with setting up production, the patents often do not do much harm. They do not obstruct most individuals who use patented products."
"I figure that since proprietary software developers use copyright to stop us from sharing, we cooperators can use copyright to give other cooperators an advantage of their own: they can use our code."
"If you want to accomplish something in the world, idealism is not enough — you need to choose a method that works to achieve the goal. In other words, you need to be pragmatic."
"The programmers who write improvements to GCC (or Emacs, or Bash, or Linux, or any GPL-covered program) are often employed by companies or universities. When the programmer wants to return his improvements to the community, and see his code in the next release, the boss may say, "Hold on there — your code belongs to us! We don't want to share it; we have decided to turn your improved version into a proprietary software product." Here the GNU GPL comes to the rescue. The programmer shows the boss that this proprietary software product would be copyright infringement, and the boss realizes that he has only two choices: release the new code as free software, or not at all. Almost always he lets the programmer do as he intended all along, and the code goes into the next release."
"The GNU GPL is not Mr. Nice Guy. It says "no" to some of the things that people sometimes want to do. There are users who say that this is a bad thing — that the GPL "excludes" some proprietary software developers who "need to be brought into the free software community." But we are not excluding them from our community; they are choosing not to enter. Their decision to make software proprietary is a decision to stay out of our community. Being in our community means joining in cooperation with us; we cannot "bring them into our community" if they don't want to join. What we can do is offer them an inducement to join. The GNU GPL is designed to make an inducement from our existing software: "If you will make your software free, you can use this code." Of course, it won't win 'em all, but it wins some of the time."
"If you focus your mind on the freedom and community that you can build by staying firm, you will find the strength to do it. "Stand for something, or you will fall for nothing." And if cynics ridicule freedom, ridicule community...if "hard nosed realists" say that profit is the only ideal...just ignore them, and use copyleft all the same."
"While free software by any other name would give you the same freedom, it makes a big difference which name we use: different words convey different ideas. In 1998, some of the people in the free software community began using the term "open source software" instead of "free software" to describe what they do. The term "open source" quickly became associated with a different approach, a different philosophy, different values, and even a different criterion for which licenses are acceptable. The Free Software movement and the Open Source movement are today separate movements with different views and goals, although we can and do work together on some practical projects. The fundamental difference between the two movements is in their values, their ways of looking at the world. For the Open Source movement, the issue of whether software should be open source is a practical question, not an ethical one. As one person put it, "Open source is a development methodology; free software is a social movement." For the Open Source movement, non-free software is a suboptimal solution. For the Free Software movement, non-free software is a social problem and free software is the solution."
"Radical groups in the 1960s developed a reputation for factionalism: organizations split because of disagreements on details of strategy, and then treated each other as enemies. Or at least, such is the image people have of them, whether or not it was true. The relationship between the Free Software movement and the Open Source movement is just the opposite of that picture. We disagree on the basic principles, but agree more or less on the practical recommendations. So we can and do work together on many specific projects. 'We don't think of the Open Source movement as an enemy. The enemy is proprietary software."
"We are not against the Open Source movement, but we don't want to be lumped in with them. We acknowledge that they have contributed to our community, but we created this community, and we want people to know this. We want people to associate our achievements with our values and our philosophy, not with theirs. We want to be heard, not obscured behind a group with different views. To prevent people from thinking we are part of them, we take pains to avoid using the word "open" to describe free software, or its contrary, "closed", in talking about non-free software."
"The term "free software" has an ambiguity problem: an unintended meaning, "Software you can get for zero price," fits the term just as well as the intended meaning, "software which gives the user certain freedoms." We address this problem by publishing a more precise definition of free software, but this is not a perfect solution; it cannot completely eliminate the problem. An unambiguously correct term would be better, if it didn't have other problems."
"The official definition of "open source software," as published by the Open Source Initiative, is very close to our definition of free software; however, it is a little looser in some respects, and they have accepted a few licenses that we consider unacceptably restrictive of the users."
"The explanation for "free software" is simple — a person who has grasped the idea of "free speech, not free beer" will not get it wrong again."
"'The main argument for the term "open source software" is that "free software" makes some people uneasy. That's true: talking about freedom, about ethical issues, about responsibilities as well as convenience, is asking people to think about things they might rather ignore. This can trigger discomfort, and some people may reject the idea for that. It does not follow that society would be better off if we stop talking about these things."
"Today many people are switching to free software for purely practical reasons. That is good, as far as it goes, but that isn't all we need to do! Attracting users to free software is not the whole job, just the first step."
"At present, we have plenty of "keep quiet", but not enough freedom talk. Most people involved with free software say little about freedom — usually because they seek to be "more acceptable to business." Software distributors especially show this pattern. Some GNU/Linux operating system distributions add proprietary packages to the basic free system, and they invite users to consider this an advantage, rather than a step backwards from freedom."
"To stop using the word "free" now would be a mistake; we need more, not less, talk about freedom. If those using the term "open source" draw more users into our community, that is a contribution, but the rest of us will have to work even harder to bring the issue of freedom to those users' attention. We have to say, "It's free software and it gives you freedom!" — more and louder than ever before."
"The Open Source Definition is clear enough, and it is quite clear that the typical non-free program does not qualify. So you would think that "Open Source company" would mean one whose products are free software (or close to it), right? Alas, many companies are trying to give it a different meaning."
"Over the years, many companies have contributed to free software development. Some of these companies primarily developed non-free software, but the two activities were separate; thus, we could ignore their non-free products, and work with them on free software projects. Then we could honestly thank them afterward for their free software contributions, without talking about the rest of what they did. We cannot do the same with these new companies, because they won't let us. These companies actively invite the public to lump all their activities together; they want us to regard their non-free software as favorably as we would regard a real contribution, although it is not one. They present themselves as "open source companies," hoping that we will get a warm fuzzy feeling about them, and that we will be fuzzy-minded in applying it. This manipulative practice would be no less harmful if it were done using the term "free software." But companies do not seem to use the term "free software" that way; perhaps its association with idealism makes it seem unsuitable. The term "open source" opened the door for this."
"Once GNU is written, everyone will be able to obtain good system software free, just like air."
