Well him and Cobana had already ended their friendship before AEW. He just got so tired of the accusations that he caused him to be fired at 1st.
While Punk has a history of edge biting promos ...a lot is gone over before they do it , the idea of the entire thing threw off the promo and made Punk question if Page was gonna continue to go into business for himself at the PPV. As Punk detailed to Helwani , they had went over what they each planned to say to each other and then Page threw it all out onscreen.Again though, the whole Page/Punk situations. The whys behind it isn't the relevant part. It's that Punk got upset over something he himself has made a career of in the business. But Punk strikes me as a person who can't take a L and move on and holds a grudge like nobodies business.
Punk wasn't happy as it was basically hurting his #1 face run to fans who would believe the internet crap. Tony refused to even say a word to Page over this and during it you had Hangman proclaiming how he doesn't need to listen to veterans on advice. It was basically FU ...me and my friends can do whatever we want and the owner won't say a word. And it seemed that way as we saw.
A number of guys there liked Punk and stood up for him. A fact one got heat (Dax) for saying everyone should think of "business" and let sh-t go. But Spears (who already comically mocked the AEW stuff) , Danhausen , FTR , Powerhouse Hobbs ...they were all guys Punk was friends with. (Max himself was one and you can tell both men loved each other onscreen given MJF has said the Punk program was his best one)I think I'll have to put in a disclaimer here that I actually quite like Punk as a performer/talker and he was one of the reasons why I did pick up AEW after his suspension (and because I wasn't going to start watching 10 hours of WWE wrestling a week), but he just has to curb himself. Because he's always come off as an unlikable ****.
