Punk is very much online, has criticized fans for taking sides and having parasocial relationships with wrestlers, and he's also had beefs with a lot of the dirtsheet writers. So he's building buzz with the people he knows will blow this kind of stuff out of the water.
It is kinda funny though that Tony Khan, every time he's been asked about Punk in the last 2 weeks, has pivoted to stuff like "Yes, CM Punk has a lot to say at the debut of Collision about reigniting his rivalry with Samoa Joe and reuniting with FTR!
" as if he's not even gonna make insider references and Punk's just ignoring that and leaning right into the drama lol
