Linus Torvalds. Richard Stallman. GNU and the GPL.

As a bit of an old-timer, I literally don't know exactly where to start a new conversation on this in a place like this; for me the obviousness of the theoretical and practical superiority of free and open source software principles are just always there for me; and it's quite obvious here that it's different for younger people.

So I'm dropping the names and the concepts. Perhaps someone else knows how to get this going?
