I don't think they give a stuff about the fans, I think it's the ivory tower people at FIFA along probably with betting/moneyball. The impact to the drama of football is, for me, too high a price to pay. At least the implementation could be sooooo much better than it really is in order to protect the spirit of football, but some think getting every decision 100% right is more important than the spectacle that is sport!
Most leagues and cups were won by the team who deserved it before VAR came along, and the odd ones that weren't... it's entertainment, not life or death! (Except for the blatent foul on Baptiste vs West Ham in the playoff final, that was a travesty which should have been overturned.
)
