The Free Software Foundation (FSF) is a nonprofit organization founded in 1985 by Richard Stallman with the mission to promote computer user freedom and to defend the rights of all free software users. The FSF facilitates the development and use of free (as in freedom, not free of charge) software – particularly the GNU operating system and its GNU/Linux variants – and campaigns against threats to user freedoms like software patents and digital restrictions management (DRM). The foundation also provides critical resources to support the development and legal protection of free software, including software licensing, compliance, and education on the benefits of using and contributing to free software. The FSF's website, https://fsf.org, serves as a hub for its advocacy efforts, offering news, a comprehensive library of free software, and other resources for both the technical community and the general public.
