It has been reported that Ticketmaster has exclusive agreements with 70-80% of US venues. It's great that you have all the choices you do. For me, in western Ohio, every major venue for hundreds of miles in every direction is an exclusive Ticketmaster venue. You can't gain admittance to any show in those venues without a phone that can run their proprietary app.

Ticketmaster is bullshit, for sure, but they're just one example of the problem of being forced to use proprietary user-hostile software.
