Honestly I think people not living the gimmick and kayfabe being dead has nothing to do with it and the only people that complain about that kind of shyt are the people who go out of their way to know all the backstage inner workings and discuss them with others on message boards like this. Everyone knows wrestling is just a show. Even at the height of the Attitude Era, the talent were rarely in full kayfabe when doing media appearances, Mick Foley's books were heavily promoted on TV and were 100% kayfabe shattering. shyt, the Attitude Era officially kicked off with Vince opening the show explicitly breaking kayfabe and saying they were changing the creative direction to be less insulting to viewers (the irony).
If anything, the lack of kayfabe off of TV and wrestlers being allowed to be real people on social media is a net benefit to fans being able to connect to them and their storylines, which are very often weaved together in some kind of kayfabe 2.0 anyway.
It's just bad writing and Vince's animosity towards his own audience. You can count on one hand the number of satisfying storylines and angles over the past like....decade. One could probably make the argument that this all really can be traced back to WWE going public and stockholders becoming more important than the viewers. Everything WWE does is to juke the numbers for the quarterly financials to work the investors for another quarter.
