Blizzard Co-Founder Mike Morhaime Reportedly Left Because He Was Tired Of Butting-Heads With Bobby Kotick

Then why'd he sell to Activision? They were doing well enough.

Lol, that makes sense. They have completely different philosophies on business. Morhaime was gaming first, Kotick was greed first.

FTA:

According to Schreier, the problems began immediately after Activision purchased Blizzard in 2007.

That makes sense. I've been in companies that changed owners. The change starts when the new people walk in, but it takes time to "turn the ship" so to speak. It will turn, but it takes time. The corruption is slow, boiling-frog style.

But Robert is such a nice man!
