Someone please explain because I’m young

I’ve been to many dead and co concerts never seen the real thing. Love listening to live dead stuff and that’s really all I do listen to. And I’ve tripped listened to it and it was magical. I’ve been through the dark stars and stuff and get it. But really what is the hate on John Mayer. He doesn’t try to be Jerry never has. He took time to adapt but it’s hard to deny the shows they put on are incredible at least to me. So someone please explain the stupid hate I see everywhere. Cuz from what I’ve seen Jerry would not approve. So where’s it coming from

Edit: seeing mixed responses. For those who dislike, would you rather there be nothing. Also are you mad the people are enjoying something that you aren’t able to anymore?
