So, what you're saying then is that it's OK for people to make money at such a festival, say, selling food/burgers/drinks, etc...but, the very people who are bringing the crowds in, in the first place, should be paid absolutely NOTHING, purely because they're musicians and don't matter?

Tell me, do you ever see lawyers, doctors, teachers, etc..offering their skills and talents for free at festivals, having spent a LONG time honing those talents to be the best?

WHY do musicians regard themselves as not being worthy of being paid?

Was the food free?
Was the beer free?

I doubt it, but the entertainment was, because SOME Musicians decide to turn up for free, without thinking what they're doing, purely pleased to share their music whilst others make a profit from their desire to 'apologize for being musicians and expecting payment'....

Yeesh!!
