Although I doubt they would buy it back, their customers all hate them, they have the worst reputation, and they've never given any shits about that. So I don't think they'll do any of that anyhow.

Maybe worth pointing out- that's a feature, not a bug.
The value Ticketmaster provides is taking the anger from fans for high prices. The performers (and producers/labels/whatever) want to extract as much value from their fans as they can, and having Ticketmaster look like the greedy badperson prevents their fans from being mad at them.
