and then they charge "winning" bands tens of thousands of dollars each to be seated at their own awards dinner

That just registered. That would be extortion, seeing as they publicize it when a band doesn't attend.

Is it a "suggested donation" or an actual bill? Can they get their award if they don't pay to be seated? Do bands get paid for performing at the ceremony?

I never donate a cent to their education program. Part of their lesson plans involve teaching kids about rap music. (I don't know much about rap music; it being part of "rock and roll" is beyond my comprehension)

I know that the Sex Pistols boycotted in part because of the fees they were to be charged.

Glen Matlock ended up playing the Hall when the Faces got inducted.
