His job, as far as I can tell, is to add listeners to the half a million he has listening to his podcast every week. He's an entertainer/broadcaster first and foremost, and their tendency is to hype up and sensationalise in order to get clicks.
He's an expert in football finance? Ok, then why is he indulging in gossip of the "I didn't hear this from the club but I heard it locally" variety? And why is he literally broadcasting what he knows to be sensitive private messaging from the club? Presumably he has at least some professional standards?
Maybe he should stick to the boring finances. Though as he said himself about his job, it is "humdrum work", so I understand his need to sensationalise and - again as he stated - even "be mean to Everton". That's just part of the job as a light entertainer on social media, I suppose.
In brief: if anyone believes Maguire to be an objective voice on EFCs referal to the PL commission they need their head feeling.
