As a customer who earns a tech salary, mostly I want to be able to go on the site, find the "best available" seats, and buy them. Done.
What Ticketmaster instead forces you to do is go through an artificial queuing system, lies to you about what's best available, has widely ranging dynamic pricing, doesn't allow you to purchase all seat classes available at any given moment and releases them randomly, and does all sorts of other horrid fuckery and at the end as an extra middle finger charges you a "convenience fee" for having you print your tickets yourself or scanning them from your phone after you went through the least convenient, pleasant, and reasonable process every to get overcharged for the tickets.
And let's be clear, we're talking about overcharging. The face value of a ticket can be high for a world-famous act. So let's say the face value of a typical seat is $250 for a concert. Ticketmaster will absolutely charge you $700 for that same ticket.
