I imagine the backlash from this will be huge, financially for Blizzard. People didn't want the single player game to force you to be online, now details have been stolen as a result of being forced to do this. I think I'm done with Blizzard to be honest. The fact that they've immediately admitted this means it's very bad. Normally they just ignore the paying customers, hoping the flak will die down, but in doing this, you know it's very serious. Clearly they do not have the ability to manage the systems they force on us.
