Richard Stallman Quotes
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.
Stallman, Richard. "Free Software Is Even More Important Now." GNU Operating System, Free Software Foundation, 2013.
Richard Matthew Stallman, also known by his initials, rms, is an American free software movement activist and programmer. He campaigns for software to be distributed in a manner such that its users receive the freedoms to use, study, distribute, and modify that software. Software that ensures these freedoms is termed free software. Stallman launched the GNU Project, founded the Free Software Foundation, developed the GNU Compiler Collection and GNU Emacs, and wrote the GNU General Public License.
