Programming is not a science. Programming is a craft.

Idiots can be defeated but they never admit it.

If 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.

Sharing is good, and with digital technology, sharing is easy.

If in my lifetime the problem of non-free software is solved, I could perhaps relax and write software again. But I might instead try to help deal with the world's larger problems. Standing up to an evil system is exhilarating, and now I have a taste for it.

No person, no idea, and no religion deserves to be illegal to insult, not even the Church of Emacs.

Talking about freedom, about ethical issues, about responsibilities as well as convenience, is asking people to think about things they might prefer to ignore, such as whether their conduct is ethical. This can trigger discomfort, and some people may simply close their minds to it. It does not follow that we ought to stop talking about these things.
