Blizzards problem isn't so much Activisions influence (Blizzard retained autonomy) as it is the loss of Blizzard North and the success of WoW permeating through the rest of the company. It is not hard to see the WoW influence in Diablo 3. If this was Blizzard they would at least publicly acknowledge it, apologize and offer refunds like they did with Diablo 3.
But anyway that's besides the point, this is all about EA being EA as usual. This is yet another in a long line of EA fuckups, totally justifying every single time they get criticized by the public and the press.
