I do not see it that Mox is being a sh1t starter and I think (although might not be correct) had a rightful position for him on the situation described. I also don't blame Punk either.
The blame goes to snowman on letting a non journalist, who doesn't work for you, be arguably a face for your company. Pre AEW, I knew about Meltzer, but I never thought he influenced fans like he does today with AEW. And that happened because Khan let it happen, and many of their faces like the Bucks and Omega and Jericho, keep lending this man credibility and seem they have no problem to stroke his ego.
Meltzer is the direct problem, but Khan and the young clowns/Omega/Jericho are the people that allowed it to happen. And that's how you have a sh1t locker room
