They own the venues. And the artists are to blame because without them ticketmaster would have no product. Pearl Jam took a huge career hit trying to fight them.
Yeah Pearl Jam did take a huge career hit trying to fight them, and that's admirable, but they shouldn't have had to do that. Why should artists carry the burden of having to sacrifice their careers to fight an illegal monopoly? That's the role of government. You may as well say that fans are to blame for going to ticketmaster-promoted concerts and buying tickets on ticketmaster because they were enabling ticketmaster. Both fans and artists are being harmed by the ticketmaster monopoly.
