I'm pretty sure Blizzard said the same thing. One of the first rules of every company is, though not said in the same way, don't talk shit about your company, and he fessed up to, talking shit about Blizzard in his first sentence.
"Yesterday, I said some very disrespectful and selfish things about the class design team at Blizzard"
I see no reason to get mad, he's accepted his fate, knew what he did wrong, and oh well. Not like the game will get any worse, or better.
