The Free Software Foundation (FSF) is a nonprofit with a worldwide mission to promote computer user freedom.
Free software means that the users have the freedom torun, edit, contribute to, and share the software. Thus, free software is a matter of liberty, not price. We have been defending the rights of all software users for the past forty years. Help sustain us for many more; become an associate member today.
