More cynicism please
A better interpretation of this would be that Murdoch is rapidly backing away from the UK side of things due to: a hostile British public and political interests; to protect his US business which is more lucrative; and to avoid being charged with bribing public officials by the US government. All real threats to him.
From my perspective I would say good riddance. It is time the newspapers were owned by a more diverse group of people to avoid all that political power being held by a small number of nasty white old men!
