People need to understand that the point of ticketmaster is to take the heat for high concert prices. That $150 ticket with $150 in fees? That's really a $300 ticket. The artists and concert promoters don't want the greedy optics of charging that kind of money. So they play the "good guys" and only charge their $150 for the Ticket. Then Ticketmaster intentionally plays the bad guy and picks up the other $150.

The money goes to the same place in the end, it's just that Ticketmaster takes the heat off the artist for charging $300 a ticket. Keeps the fans happy.

You're supposed to get mad at them, that's the point of their existence.
