It's fun for an internet forum to chat about but lets be real: no fan complaining is getting rid of VAR. No governing body is going to care one iota if the noisy rabble turn their backs and boo; the fans are 10000% utterly irrelevant in such things (plus every club has a part of a fanbase that thinks VAR is against them).
Today was so blatant an extreme that if it happened to the likes of Real Madrid you could see all those players walking off the pitch and refusing complete the game. That would be the only thing that gets noticed, and even then the club would get punished with a points fine.
Bottom line is, 1 week from now (hell, 1 day from now) it wont even be talked about in the media. Mistake made, shrug shoulders, says "oops our bad, sorry bout that", then on to the next.
