I have been to Ticketmaster events that use reasonably priced, printable tickets, you could even buy a printed ticket with cash. In fact, even though there are so many Ticketmaster events, they are not all working the same way. And Ticketmaster doesn't have the monopoly on shitty practices, the article gives a good example in the beginning.
What I suspect is that Ticketmaster is nothing more than a service provider. The venue/event organizer/... looks at the Ticketmaster catalogue and pick the product they want. There are "evil" products in that catalogue, and they are probably the ones with the best returns, but I am sure people have a choice.
I'd even go as far as calling Ticketmaster "Evil as a Service". So people can say "fuck Ticketmaster" instead of saying "fuck Taylor Swift". I would be very surprised if artists (and their agents) at the level of Taylor Swift didn't have a say regarding ticket sale practices, even with Ticketmaster.
Of course, the monopolistic practices of Ticketmaster are a problem, people are most likely paying more than they should because of it, but all the crap with apps, resale platforms, etc... I am pretty sure the event organizers, maybe the artists themselves are as much to blame.
