TBH, I don't really care about ABK franchises as much as I rarely play their games. It is just that these purchases set the wrong precedence because of their anti-competitive nature.
And apart from the studio shakeup, there are a ton of other things that are eating the Xbox division day by day: Game Pass has done more harm than good, third-party support is drying up because of lower console sales, lower console sales are because Xbox is focused on Cloud and does day-one PC releases, lower market share makes it difficult to get third-party exclusivity and marketing deals, poor localization in non-NA regions, poor marketing of their games, 18-month contractors in all studios to save money ...
There are just a lot of issues that they will have to fix first. And they refuse to resolve those issues and then complain about the low market share as a justification to buy more publishers. I hope the same as you -- that it doesn't happen because Xbox's current position is Xbox's own fault.
