It's clear that other problems such as [...] the domination of business over government, science, thought, and society, are much bigger than non-free software.
Richard StallmanIf the users don't control the program, the program controls the users. With proprietary software, there is always some entity, the "owner" of the program, that controls the program and through it, exercises power over its users. A nonfree program is a yoke, an instrument of unjust power.
Richard StallmanFree software' is a matter of liberty, not price. To understand the concept, you should think of 'free' as in 'free speech,' not as in 'free beer'.
Richard StallmanI 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.
