Richard Stallman in an interview on LinuxInsider
The idea of the free software movement is that software users are morally entitled to four essential freedoms, essential for living as part of a free society where people can cooperate when they wish:
- Freedom to run the program, as you wish.
- Freedom to study the source code, and change it to do what you wish.
- Freedom to make copies and distribute them to others, when you wish.
- Freedom to distribute modified versions, when you wish.
Instead of giving priority to freedom and community, the open source philosophy agrees with Microsoft that what matters is making software powerful, reliable and convenient.
People who hold those views have a right to their opinion. I disagree with their opinion, so I vociferously object when people label me or GNU/Linux with the slogan open source.
Anyone committing aggression with software patents deserves bad things to happen
