Why do some wrestling fans not enjoy AEW?

For non wrestling fans AEW (All Elite Wrestling) is a wrestling promotion founded in 2019 to compete with WWE after years of fans complaining about how bad WWE has been.

They've been listening to the fans feedback, the in ring work is fantastic and they have the best roster of any wrestling promotion nowadays.

Yet for some reason some WWE fans insist it's bad and they never explain why, my theory is they're attached to WWE and don't wanna see a competitor thrive
