Regarding piracy, that is already heavy discussed by top politicians. Across nations.. And there are censorship already, because of piracy. Pirate sites will face something similar even sooner, and next to come is the huge flow of porn which is not self-regulated good enough. If you don't think it will happen? That's fine. But don't be surprised.
