1) what other platform? I'm not too intimate with this, but part of the revolt over the Taylor Swift contrversy came from how Ticketmaster as exclusive use to most of the big venues. That seems to be the other half of the issue not talked about in this article.
2) I thought this issue would be as simple as banning resales, but after reading the kind of tech (and money they pay) to invest in the scalping... idk. It'd kill off the casual scalping of someone who buys maybe a half dozen tickets. people paying hundreds for fake numbers and specialized browsers won't be deterred. And the demand for the tickets comes from the celebrities, so it's a pretty safe market as long as the concert industry stays up (so, no more COVID. Even then, it's not like it's hard to pull out).
