Blaming Phil Spencer is kinda crazy when he is basically the only reason Xbox is still here, he fought to keep the suits from shutting it down years ago .
PlayStation is just a Monster that you can't eat for breakfast even Nintendo ran away from direct competition in the console market with PlayStation while Xbox was dumb enough to think they had a chance because of all the money they have to throw away. Xbox just failed to create their own market instead of trying to take the market that PlayStation opened up.
Now they want to take the market that Steam , Android & Apple Opened up.
There is room in the market as long as you bring something different to the table like Wii , Switch, Meta Quest.
Kinect & Series S would have a market to itself right now.
