Asides from Phil Brooks the person confirming he's a complete hypocrite, this is ultimately a good thing for both WWE and AEW.

For WWE, I'm sure they will have a better ability to control his bullshit, and he may even be able to teach a few people a thing or two given the performance centre. Personality problems aside, Punk is a solid worker. It also gives ardent Punk fans something to watch with him on.

For AEW, it should reduce potential future hijacking by grumpy Punk fans, and hopefully stop the rumour mill distracting from the show.

For Punk, well, honestly, I can't see much beyond him getting fed to Roman. And the money, obviously.

I give it a year.
