Richard Stallman Richard Matthew Stallman (born March 16, 1953), often known by his initials, RMS, is an American software freedom activist and computer programmer. He campaigns for software to be distributed in a manner, such that a user receiving it, likewise receives with it the freedoms to use, study, distribute and modify that software: software that ensures these freedoms (on receipt) is termed free software.
Stallman has suggested that the United States government may encourage the use of software as a service because this would allow them to access users' data without needing a search warrant. by Mar 13
