No, they invented rules to say he violated something. It was a cover to kick him out because Trump didn't like him. There was no warning. Not to mention the irony of attacking Acosta for interrupting when he could barely get three words out without Trump talking over him.
Acosta won. The White House restored his pass.
Trump often had to be reminded he's not running his little hotel. He can't just kick people out of the White House because he wants to. The constitution puts limits on him he wasn't used to.
Your defense of this demonstrates you don't actually have a problem with cancel culture. You have a problem with your side being "cancelled".
