And because Valve made it clear that purchasing doesn't provide ownership then piracy can't be theft.
It's copyright infringement, not theft. The media industries just want to guilt trip consumers into thinking it's theft, but it's not. Neither legally nor actually.
Pounds of sarcasm, in case this wasn't clear.
Cases will be brought before judges based on money. Big pirates that are somehow making money doing it will be brought in front of a judge and some love will impact them.
Anybody hypothetically pirating one steam game to play for themselves because they felt alienated by Steam isn't going to be dragged in a judge.
