Short answer: Yes.
Longer answer: Oh, hell yes.
Xbox fans like to talk about Phil being the Xbox savior, when in truth, he's part of the problem. He was there through the DRM fiasco, and we didn't hear a peep about his dislike of it. In truth, he was probably one of the ones who either helped push it forward or was at least ok with it.
Really, I think it could just be a case of him being a complete yes man. Do we actually believe Phil, who was around during the strong 360 years, wanted all of his exclusives to go to PC? Highly doubt it. That was Nadella, who doesn't care as much about HW, as his background is in online services. And the xCloud/GamePass directive is definitely coming from above Spencer. Even at the cost of game quality.
And I think it's safe to say, Phil being a gamer is just another false persona of his. He actually thought that Halo gameplay clip looked great, just because it was in 4K/60FPS. Polygons, texture resolution, animations? "Who cares. The overall output is 4K/60FPS, it's great looking."
Xbox fans have been praising this yes man with empty promises for long enough. It's either time for someone else to take over, or just put GamePass on other systems and be done with it.
