I‘m actually not sure this statement is true. “The goal is ultimately entertainment” is a thought terminating cliché. What about sportsmanship, competition, beauty, experiencing a common cultural phenomena with the entire world, etc?
But even if this statement is true, FIFA needs to learn from the failure of Eurovision and see that people are not entertained by watching a rigged game. For competition to be fun, it has to be fair.
You see where I'm going with this? I just can't seem to get upset that a red card that isn't a red card for other teams is getting rescinded.
I've literally been watching for decades and nobody seemed to care before.
A ref got a call wrong and that's ok and should be doubled down on according to UEFA. Well, UEFA can just view this as the disciplinary committee getting it wrong and they can just live with that.
WWE is not an apples to apples comparison, as it is widely known among fans that the spectacle aspect of the sport weighs heavier then the competition aspect, as such both the fighters and referees play loosely with the rules to maximize the spectacle aspect. The same is not true of Eurovision, and it for sure is not true of the World Cup and the game of soccer in general.
