Who did more damage to Xbox's console business: Don Mattrick or Phil Spencer?

I don't buy the whole ''Xbox one meant Xbox had no chance in the future against Playstation''. A console gaming company can turn around failures. I mean the Wii U was a bigger bomb from a sales perspective than anything Xbox has ever had, and yet they could turn it around with the Switch and sell incredible. It was totally in Xbox and Phil Spencer's power to be competitive against the PS5, whatever happened during the Xbox one era. They fact that they continued to decline from Xbox one was not inevitable.
