"Free Unix!" This was the slogan with which Richard Stallman, on September 27, 1983, announced the plan to develop the GNU System. "I consider that the golden rule requires that if I like a program I must share it with other people who like it. [...] I have decided to put together a sufficient body of free software so that I will be able to get along without any software that is not free." https://www.gnu.org/gnu/initial-announcement.html #GNU40
