Online game subscriptions are taxes to the dictators. They run the country and they set the rules, but your membership is entirely voluntary. Nobody makes you play WoW, unless you are a poor gold-farming slave, I guess.
So how far can the dictators go before the players start leaving in droves? Why would they want to do such a thing? Well, in the end it might not be a conscious choice the dictators make. With absolute power comes absolute corruption. They won't all turn out like that, especially because it's in the best interests of the company to keep the game fun to play rather than a steaming pile of bureaucracy or corruption, but it could happen.

PS - I have recently suspended my City of Heroes subscription.
PPS - But that was because I didn't have time to play any more.
