2. A slogan associated with Unix in the romantic days when Unix aficionados saw themselves as a tiny, beleaguered underground tilting against the windmills of industry. The “free” referred specifically to freedom from the fascist design philosophies and crufty misfeatures common on competing operating systems. Armando Stettner, one of the early Unix developers, used to give out fake license plates bearing this motto under a large Unix, all in New Hampshire colors of green and white. These are now valued collector's items. In 1994 DEC put an inferior imitation of these in circulation with a red corporate logo added. Compaq (half of which was once DEC) continued the practice.
