Technically they were not found guilty. They agreed to give states and the lawyers and out of court settlement into the millions. The consumers were "promised" a check (if they didn't get a whole lot of responses to the offer for a free check, no questions asked). Consumers didn't get a check.
Since it was an out of court settlement, they were not found guilty in a court of law of price fixing. We all know they did.
I heard different, that they lost the case.
But anyway, the RIAA is guilty of so much more than what is listed in this lawsuit.
