You know what, he might be a bit of a bell and he would no doubt introduce some things that would drive fans nuts (BMD being plastered with Sports Direct and Frasers branding for example) but he would get the club making money because that's what he does.
Getting a club making money is not what he does. Getting Mike Ashley making money is what he does.
Newcastle's commercial revenue was 27.6M when he took over in 2007 and had only increased to £29.1M by 2020 when he sold up 13 years later. That's an absolutely pitiful performance for such a big side in a one club city and more so taking inflation into consideration. For context this is a club that at the turn of the century were the 5th highest revenue generating club in the world and second only to Man Utd in terms of revenue within the UK.
Under his stewardship the club was relegated and made astute decisions such as bringing in the dream team of Dennis Wise and Joe Kinnear. Giving Alan Pardew and his entire backroom staff 8 year contract extensions was another great idea until they were sacked 2 years later with the deals being paid out in full. Then he brought in Steve McLaren and others of that calibre.
And that's before you get into the full picture of what him being a bell actually is. Putting the entire non-first team staff at Newcastle on furlough during the Covid lockdowns was shameful and he has a long history of contempt for workers rights. He's a pretty abhorrent individual judging by the noise around him. You can't claim to give a toss about Everton football club and want someone like him anywhere near it - they are two entirely incompatible stances.
He may well have offloaded the club into incredible wealth (at a moral cost - but not entirely relevant to this) but it wasn't a matter of him holding out for the best deal for Newcastle. He spent over 10 years trying to get rid at a price that worked for him, not what was right for the club and was quite happy for the club to aimlessly drift so long as his finances didn't take a hit. He would have put it into the hands of anyone so long as he himself made enough dough.
If someone like him ended up anywhere near the club in any capacity Sports Direct adverts would be the least of the issues. We'd be tenants in BMD. He's had no issue whatsoever with serving Coventry an eviction notice from their ground and would have no issue with doing the same to Everton Football Club.
