As the old joke goes: “Software, free. User manual, $10,000.” But it’s no joke.

Freedom and community are important. Gratis software is not worth such an effort, because price is usually not an ethical issue. Paying isn’t wrong, and being paid isn’t wrong. Trampling other people’s freedom and community is wrong, so the free software movement aims to put an end to it, at least in the area of software.

Free software permits students to learn how software works. Some students, on reaching their teens, want to learn everything there is to know about their computer and its software. They are intensely curious to read the source code of the programs that they use every day. To learn to write good code, students need to read lots of code and write lots of code. They need to read and understand real programs that people really use. Only free software permits this.
Proprietary software rejects their thirst for knowledge: it says, “The knowledge you want is a secret — learning is forbidden!” Free software encourages everyone to learn. The free software community rejects the “priesthood of technology”, which keeps the general public in ignorance of how technology works; we encourage students of any age and situation to read the source code and learn as much as they want to know. Schools that use free software will enable gifted programming students to advance.

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.

When we speak of free software, we are referring to freedom, not price.

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.

Sharing the code just seems like The Right Thing to Do, it costs us rather little, but it benefits a lot of people in sometimes very significant ways. There are many university research projects, proof of concept publisher demos, and new platform test beds that have leveraged the code. Free software that people value adds wealth to the world.

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.

Isn't it ironic that the proprietary software developers call us communists? We are the ones who have provided for a free market, where they allow only monopoly. … if the users chooses this proprietary software package, he then falls into this monopoly for support … the only way to escape from monopoly is to escape from proprietary software, and that is what the free software movement is all about. We want you to escape and our work is to help you escape. We hope you will escape to the free world. The free world is the new continent in cyberspace that we have built so we can live here in freedom. It's impossible to live in freedom in the old world of cyberspace, where every program has its feudal lord that bullies and mistreats the users. So, to live in freedom we have to build a new continent. Because this is a virtual continent, it has room for everyone, and there are no immigration restrictions. And because there were never indigenous peoples in cyberspace, there is also no issue of taking away their land. So everyone is welcome in the free world, come to the free world, live with us in freedom. The free software movement aims for the liberation of cyberspace and everyone in it.

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.

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.

We want to replace proprietary software, with its unjust social system with Free Software and its ethical social system. And so we develop free replacements for proprietary software, and other free programs whenever we get an idea, so that the world can live in freedom. The part that uses computers, at least, in that one area of life. Because winning and maintaining freedom in general is a much bigger, much broader and harder activity, but this is one part of it.

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.

Spreading the idea of freedom is a big job — it needs your help. That's why we stick to the term "free software" in the GNU Project, so we can help do that job. If you feel that freedom and community are important for their own sake — not just for the convenience they bring — please join us in using the term "free software".
