“Since we founded the free software movement, over 23 years ago, the free software community has developed thousands of useful programs that respect the user’s freedom. The programs are in the GNU/Linux operating system, as well as personal computers, telephones, Internet servers, and more. Most of these programs use the GNU GPL to guarantee every user the freedom to run, study, adapt, improve, and redistribute the program,” said Richard Stallman, founder and president of the FSF.
