Welcome — Free Software Foundation — working together for free software

You deserve to use software that is: free from restriction, free to share and copy, free to learn and adapt, and free to work with others. You deserve free software.

The FSF advocates for free software ideals as outlined in the Free Software Definition, works for adoption of free software and free media formats, and organizes activist campaigns against threats to user freedom like Windows 7, Apple's iPhone and OS X, DRM on ebooks and movies, and software patents.
We promote completely free software distributions of GNU/Linux, and advocate that users of the GNU/Linux operating system switch to a distribution which respects their freedom.
We drive development of the GNU operating system and maintain a list of high-priority free software projects to promote replacements for common proprietary applications.
We build and update resources useful for the free software community like the Free Software and Hardware Directories, and the free software jobs board. We also provide licenses for free software developers to share their code, including the GNU General Public License.

A strong free software movement focused on the principled issues of software freedom — and a strong FSF in particular — will determine what freedoms the next generation of computer users enjoy. At stake is no less than the next generation's autonomy.
