Taylor Swift explicitly put the blame on Ticketmaster for the entire 2022 fiasco [0][1]. There was no taking responsibility, and she certainly wasn't avoiding Ticketmaster during that event. If she's avoiding a relationship with them in the future (I can't find any evidence of that), I'd wager it's because of their technical incompetence in handling her volume, not the sale price and the scalpers.
But Verified Fan isn’t universally applied. The individual artist make separate deals requiring it or not and they take the blame for the hassle of requiring it. I suspect but don’t know that Tickmaster also takes a larger cut for the “overhead” of Verified Fan, making this a classic monopolist lose lose situation.
