the part about pearl jam is what should interest you. It talks about why it is so hard to move away from ticketmaster for an artist. And you can assume the same for a venue if they decided to host a non ticketmaster or livenation show. Those companies may in turn refuse to host future higher paying shows at that venue. Unethical but it has allegedly taken place. Just for reference, but I agree there needs to be a change.
I don't know much about college venues but that seems like a promising idea to focus on.
