There is a few things to unpack here. So I do apologise for the longer message. It all depends on whether we want a football pyramid or an American style sporting structure.
This extra revenue which would be skewed towards the bigger clubs at the top of the pyramid, and jeopardises the the whole structure of the game.
As the want to increase revenues is why the big 6* tried to create the European super league. And if you continue to grow the revenues of the biggest earners then they leave to form a new league. The other club's below will be evaporated.
Should these extra revenues the league make in broadcasting go into grass roots or unevenly distributed to the top clubs? As the premier league clubs keep voting in favour of.
Man City will state their academy is grass roots, but all it's doing is depriving smaller entities the opportunity to grow their own talent and forcing them to close.
Then we have type of owners profits/debt is more complex, but even the super rich generally don't have the cash funds to buy these things outright most of their assets being in no-liquid form. And discouraging the mega rich from using credit and only purchase other companies on a cash basis would harm the banking systems and weaken economies.
Who cares if they are bringing in extra revenue through sponsorship, it’s money into the game, surely better than running clubs through debt and paying interest which is money out of the game.
Why should owners be discouraged from growing their business with their own money in favour of owners like the Glazers and Kenwright who buy the club on debt and get the club to pay back that debt and then spend zero letting the club decline but still able to cash out at huge profit.
