Ticketmaster handles all of the irritation-causing aspects of the ticket purchasing and allocation process, serving as a scapegoat or punching bag for the public to hate while the artists come away clean from the bad PR. Taylor Swift doesn’t want to sell concert tickets directly to her fans because inevitably many of them will be disappointed when, for example, the stadium sells out within 0.3 seconds of starting the sale, or when logistical issues arise. When things go wrong, she will be blamed. Instead, artists prefer that Ticketmaster be assigned the “bad cop” role of handling all that stuff, and the artists get to pretend they have nothing to do with the concert-goers bad purchasing experience or disappointment.
