Cited on

id Software first released the Wolfenstein 3D source under a limited-use license and later relicensed it under the GPL: the repo's LICENSE.DOC is the "LIMITED USE SOFTWARE LICENSE AGREEMENT", and John Carmack wrote in 2009 that he released the source "originally under a not-for-commercial purposes license, then later under the GPL", and in a 2011 mail, quoted in Debian's wolf4sdl copyright file, "Yes, we relicensed it under the gpl years ago." No source here dates the relicensing.		Dev blog
