Based on what? This just feels like baseless conjecture given she hasn’t been at Microsoft for that long.

I don't think a long time executive leaves, and the expected successor (Sarah Bond) refuses to suceed because of some intimate backstabbing behind the scnes. Especially not by an executive who was previously running the AI division during an AI gold rush.

Occam's razor: Spencer and Bond jumped off a sinking ship, Asha wasn't doing enough in AI. Push her to be the fall gal for the sinking ship and put in whoever will milk AI more in her place. Win-win. Asha will be gone in a few years with her job done and a cushy parachute, and Xbox will be a shadow of its former self. But that's not a failure; that's the goal.
