Founded 1989 · Software-patent and interface-copyright reform group
The League for Programming Freedom was founded in 1989 by Richard Stallman to oppose software patents and the extension of the scope of copyright, uniting developers of free and proprietary software alike. Its campaigns included the “Burn all GIFs” protest against Unisys’s enforcement of the LZW compression patent, and it published a newsletter, Programming Freedom, in eleven issues between 1991 and 1995.
