There are talks within AEW starting from Tony Khan that if Punk in any way talks bad about AEW or references them in bad light while in WWE, his legacy in AEW will be erased. All the vids on youtube will be gone, he won't ever be recognized as AEW Champion ever. They will erase his very existence in the company. High Rank people like Jericho and Moxley are in full support of this idea. People like Taz and Mark Henry were said to be against it and wants everyone to move on and just accept what happened at All In.

Supposedly this was sent to Punk's camp and he is aware of the consequences if he decides to trash talk AEW in any way shape or form.
