While I get the point that smaller clubs won't have as many supporters and thus lower income from ifollow etc, I fail to see how this is any different from normal. Larger clubs get bigger crowds through the turnstiles.
So their income from matches will be reduced, but so will that of every other club either due to lower price compared to a match ticket or lack of F&B income, or maybe less people following online than would be at a game. But each club will have budgeted for their respective incomes and thus have the same problems. So either players already at the club on a set wage will be taking up far more of the budget giving less room for manoeuvre or players coming in will have to be on cheaper wages to match this lower income.
It's the same for everyone.
