So if I make a better car using customer feedback is the rights to the car really theirs because it was their opinions that went partially into the end product?
IP is a joke anyway. If you put information out into the world you don't own it. Sorry, you can't have it both ways. You can simultaneously support torrenting movies (I do, and I assume you do too), while also claiming you own your comments on the internet and no one can "pirate" them.
