BSD or GPL in the ideal world?

This Slashdot comment probably summarizes the difference of intent between and BSD and GPL as succinctly as one can. Every person who is unclear about the licence to use in his code, or has been a blind follower (“Should be the right one, because everyone seems to be using it”), should keep this at heart.

… when the only two ways to release software are BSD and GPL, the GPL will no longer be necessary, but we are not there.
