No different than what numerous other publishers are doing, including Sony.
And MS has pledged to keep games like CoD on PlayStation. And they wouldn’t bother to remove the games from mobile or PC.
Again, big bag of nothing.
edit, on the front page of this forum right below this thread there is a thread where you are wanting Sony to buy FromSoftware, who made basically the only great game of 2022 thus far and have consistently provided amazing multi platform games. Unlike Microsoft, if Sony were to buy FS, it actually would remove games from the competition because they sure as hell wouldn’t make the games on Xbox and even PC would be delayed. So I guess it isn’t a negative if Sony does it
