I think we can all agree that both companies have terrible management in different ways.

But this dream that MS will just clean house with Act/Blizz management is just that. If MS replaces all of senior management over the next year or two, the studios will grind to a halt. Someone has to make decisions about resource allocations. I'm dubious about the competence of senior management in general but someone has to decide the dev budget, the marketing budget, feature set, etc. And someone has to make decisions midstream when it becomes clear your battle royale game will get lost in a sea of Fortnite clones.

If MS starts firing these guys, they'll see the writing on the wall and go elsewhere on their terms, leaving the company unable to make those decisions. I just can't see MS firing anyone but the top guys.
