See, I don't mind DRM on my consoles as long as the game is functioning.
But on a PC, people send personal emails, they check their bank accounts and pay bills, they have photos and private documents like CVs.
Who wants an unknown programme that could be hacked to steal that data. Or even if an unscrupulous company on employee steals that data. What if the decide they want to watch what I'm doing, measuring my usage? To me that's just too much of a risk so I WONT buy that game, I will vote with my feet.
Personally I'm that that bothered, I have an awesome firewall that controls all network connections, no application can connect to the internet without my say so. Even piggybacking other programmes can be seen.
If a game requires a constant internet connection to be played then that is ridiculous. Moreover, good luck taking it to court. It will be difficult to submit the evidence to a court, in the UK at least. It's not as simple as waiving your right to privacy by default when you play, that would be an easy point to defeat.
