It's nothing to do with piracy. It's to stop you reselling your game. If this works, it comes to a console near you, very soon.
For some odd reason a lot of console gamers seem to think that what's happening in PC gaming doesn't affect them. It does, it's just a couple of years ahead. Make a stand now before it gets much, much worse. Forget the petty tribalism and THINK. Above all, write to UbiSoft, let them know why you're not buying games from them any more and avoid games with this crap on it like the plague.
