Endorsements have never been without the blessing and influence of the owner of that paper or institution. The extent that an owner lets the editorial team pick an endorsement is the same extent to which they align philosophically. It's an illusion of choice or independence.
If papers were meant to be more neutral, I suppose they would need to be owned as cooperatives by the subscribers themselves, assuming the subscribers were balanced and philosophically diverse.
