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.

Now that corporations dominate society and write the laws, each advance or change in technology is an opening for them to further restrict or mistreat its users.

Control over the use of one's ideas really constitutes control over other people's lives; and it is usually used to make their lives more difficult.

Programming is not a science. Programming is a craft.

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.

Android is very different from the GNU/Linux operating system because it contains very little of GNU. Indeed, just about the only component in common between Android and GNU/Linux is Linux, the kernel.

My favorite programming languages are Lisp and C. However, since around 1992 I have worked mainly on free software activism, which means I am too busy to do much programming. Around 2008 I stopped doing programming projects.
