You're thinking too hard about this. He's giving an honest interview. He's not cutting a "watch my match please" promo in character trying to get heat. You don't have to go out of your way and actively search out these interviews. Nobody is making you.Matches are fake, therefore matches are kayfabe.
If you think kayfabe is dead then you’re saying wrestling matches are real.
MJF and AEW in general do kayfabe really well in the modern environment.
It’s not that hard IMO.
Drew calling Brock a genius doesn’t make anyone want to see Drew win a fake fight for the top title.
