You are right, it is without a doubt the influence of American sports ownership. To be fair to us American fans though, most of us hate this type of shit too. We just have no power to stop it, there is way, way too much money in American sports for ownership to give a shit about what their fans think. I would LOVE to have a culture closer to the English football culture but it's just not in the cards.I was going to say similar, but didn't want to offend the Americans we have on here.
As an example, the baseball team I support was purchased a decade ago by a billionaire family. The family is closely linked with Trump and has used the facilities themselves for Trump fundraising events. They also launched their own TV network in conjunction with a notoriously conservative media company in the U.S. Our stadium is one of the few that is a "neighborhood" stadium where it's built right in a small community; ownership has been systemically buying every building they can in the area and replacing many of the small local businesses that used to exist there with corporate chains.
I hate just about every aspect of it but I am powerless to stop it. Sure, I could stop watching the games but I'm a single drop in a bucket. There are occasionally small protest groups that will spring up in American sports but they are universally ignored by ownership.
Anyway, I did just want to say that I hope this change does not happen and that I think most American fans would agree with me. Really this is just another example of how money and greed can ruin beautiful things.
