That’s a bit too broad, as I am not sure even those that believe the PL is a bastion of moral and ethical excellence would answer ‘no’ to that (there is overwhelming evidence that football writ-large is corrupt; even the formation of the Premier League itself is an example).
And, anyway, the main questions being posed in this and several related threads recently merged in to this one are regarding the Premier League, so the question is focused on that. ‘Premier League’ is a catch all for many of the entities you listed (it’s comprises many different organisations, not just League execs).
