Disagree here.
I think a lot of the pro-MS/Activision people are simply gamers who fit into one or more of these bullets:
1. Dont give a shit at all (a lot of gamers dont even play COD or Diablo)
2. Xbox/PC gamer with GP who now might get tons of Activision games on sub plan so they can save money (a good deal)
3. Stick it to Sony
Not even the most diehard Xbox fan knows PS isnt going anywhere. So you can cut out the hyperbole.
MS has tried tons of deals, S/X, first party games on GP, EA Play, One X etc.... and it hasnt improved their market position one bit. And I doubt COD will either, especially since the game is still on PS for years (including a 10 year offer), will come to Nintendo and spread to gamers using mobile. If anything, COD is diversifying across platforms, as opposed to trying to consolidate everyone into buying an Xbox where MS cuts the cord and only has it there.
MS even had COD partnership deals during the 360 era and they still finished third.
As for sticking it to Sony, hey some gamers like to troll. To be fair, which platform gamer likes to brag about most sales and profits and GOTY awards? Sony gamers. So hey, if an Xbox gamer wants to chime back saying MS owns Activision and controls the games (which they will have 100% full control after and deals/remedies are done) then that's the comeback.
