Nothing to do with player power. Our squad is massively different to a few years ago. Ten Hag simply isn't Ineos' guy, they took over and want to change how things operate and the role of the manager, and Ten Hag was always on thin ice. This is them going in a different direction which is fine. They will change the squad in due course too but it doesn't mean you stick with a manager the previous regime hired who you don't believe in, while also drastically changing his role from before.
Clean break is better, fresh start as a club.
