My personal issue with this sort of shady shit is if you allow the door open a crack to cheat in one way, it's going to be broken down by the number of other clubs that follow suit.
And although it might be the slippery slope fallacy in my own mind, and you have to be careful with that logic, if a clubs willing to cheat in these ways (fake attendance figures, sponsorships, shell companies signing youth players like city did) what OTHER methods are they going to use to cheat? We have already seen how corruptible FIFA and UEFA can be with the world cups in Qatar and Russia. What about actual doping not just financial? Media bribery? Regulatory capture? Do we turn a blind eye to those issues as well, because City only got a 50k fine for their players missing doping tests. Will Newcastle suddenly "miss" them this season too?
I hate cheating with a passion in all its forms, lads, and I am somewhere on the Rorschach spectrum of totalitarianism when I think about what we should do in response to it. The only power we've got as fans is "not to watch" or play the game at all, unfortunately, and I wonder if that indifference will finally catch up to the sport.
