American software freedom activist, short story writer and computer programmer, founder of the GNU project
Richard Matthew Stallman (born 16 March 1953), often known as rms or RMS, is the founder of the Free Software movement, the GNU project, the Free Software Foundation, and the League for Programming Freedom. He also invented the concept of copyleft to protect the ideals of this movement, and enshrined this concept in the widely-used GPL (General Public License) for software.

When I released GNU Emacs and people started using it, they started sending me improvements in the mail. So I would get a message with a bug fix, and a message with a new feature, and another bug fix, and another new feature, and another... and another... until they were pouring in on me so fast that just taking advantage of all of the help people were giving me was a big job. Microsoft doesn't have this problem.
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".
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.
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.
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.
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.
'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.
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.
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.

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.
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.
