Everybody and everything associated with Activision Blizzard could die and/or disappear tomorrow, and I wouldn't lose a wink of sleep over it. If anything, I would sleep more soundly. Maybe someone could search the wreckage later and salvage the old Sierra IPs that are still trapped under the ownership of Activision Blizzard, but other than that, I can think of nothing else of value that will be lost.
Also, I'm a pretty cynical person, I freely admit it, but I can only aspire to be as cynical as Woolie and Pat are in this video. Yeah, Kotick's golden parachute will light up the sky like a penthouse suite in Trump tower.
From one of the comments under that video: "The only black book I want that man in is the Death Note."
