Blizzard is, as many have already stated, a company. Let me say this again: Blizzard is a company. Of course they are gonna do everything they can to make money. It would be very poor management if they didn't. Can it be seen, if you look at their features and changes? Of course it can. I mean, most of us are not blind nor are we stupid. Making as many as possible happy increases your profits, most of the time anyways. So that is, and should be, their goal.
