Hard to tell considering they have a monopoly on the original purchase industry (most venues, and I'd venture to guess 90%+ of venues that would actually attract large acts) <strike>and the reseller industry as well </strike>. The worst is going to the box office to buy a ticket and being told that they can't sell the ticket at the box office, you have to buy through TM or you have to pay the same fees as if you bought through TM's site / services.
Regarding your last point (and also from the POV as someone who works in ticketing but not for TM) -- many organizations I work with (non-TM venues) and for are now transitioning to a lower unified fee structure. That is, a single fee that is the same no matter the sales channel. This trains our customers to expect a small fee at all times, we can keep that fee very consistent, and is often more in line with the nature of the agreement held with the performer regarding net adjusted gross income.
