Free Software Advocacy promotes the use and development of software that is freely available for anyone to use, modify, and distribute. This movement emphasizes the importance of user freedom, privacy, and collaboration, encouraging individuals and organizations to support software that respects these principles. Key figures in this movement include Richard Stallman, who founded the Free Software Foundation to raise awareness about the ethical implications of software ownership. Advocates argue that free software fosters innovation and community engagement, allowing users to take control of their digital lives without being restricted by proprietary software licenses.
