1) Proper citation: the person who creates a derivative work cites the source properly. 2) Free as in beer 3) A social structure where it is about ego/glory rather than money Btw ... this is loosely how academia works. Most scientists are in it for the thrill of discovery and glory (we know we can get paid better elsewhere). We kill ourselves trying to get papers at the top conferences - because that gives us and our work the highest visibility. We mostly give away our knowledge for free (this is contentious because of high undergrad tuition and patent happy universities - that said, this doesn't directly go into the scientists pockets). An excellent related quote (I think from Liar's Poker): Money doesn't matter. That's just how we keep score. Academia is essentially the same. Replace money with # of citations, journal prestige, h-index, etc.
