It's not surprising. Blizzard is an enormously unpopular studio right now that is widely seen as having grossly mishandled their product.
Some developers always get the benefit of the doubt, and some developers are universally disliked to the point their product is panned before its even released.
Blizzard, over many long years, have managed to go from the former group to the latter, and it's difficult to argue it isn't by their own doing.
