This is only part of the issue
The other side of it is the amount of data games companies are collecting about us. There was a series of recent articles in PC Gamer, Escapist and others (but not el Reg, surprisingly) about EA's Origin system. The EULA specifies that they can collect information from your PC pretty much at will without prior notification If that gets hacked (and there's a pretty good chance it will, given that even Steam got hacked) a lot of info is going to wind up in the wrong hands.
Origin in particular is worrisome as the data collected is shared out to 3rd parties as well. So it's all very well if EA's servers are like Fort Knox but GameAdServersTrololol are the digital equivalent of a hooker's knickers.
