On the internetz you get something for nothing and your mind wants to give something back. You do something because you want to, not because you have to.. Its a ****ing utopia, that developed all by itself, people had free hands and this is what came out.
Look at the ps3 scene, there are people, who spend days/week/months/years studying how the console works, studying sdk to develope software and expecting NOTHING in return. Where do you see this in the "real" world, where nothing is for free, and you do what you do because you have to...
What if this attitude spreads outside the internetz and no one will need money anymore and work as a slave to support his/hers family?
That is what triggers SOPA, ACTA and similar **** that want to "regulate" the internet, before it comes out of control
Pirating has nothing to do with it.
