There are good and understandable reasons to not want to be in the games business. Game studios are frequently a hot bed of sexual predation and just horrifyingly bad management in general. But it's a business with a large customer base that wouldn't be customers otherwise.
Microsoft has spent tens of billions of dollars acquiring game studios and their IP. They're going to have to make a decision to cultivate growth in that business or sell it for whatever they can get for it. Neither of those choices will be easy to execute well.
