Apparently revenue from these PPV games is going to the PL to help support the clubs.Obviously the split is not disclosed but I would be surprised if the clubs will see a lot of it.
I suppose it's not bad for an Arsenal supporter who pays , lowest s/tkt price, £47.00 per game but for the lesser s/tkt costs it does, as you point out, form a much higher proportion of the normal attendance price.
I pay £41.00 per month for S/Sp and BT so, at that price, it's relatively expensive - equivalent of less than 3 games -when I can watch umpteen should I wish.
