These days the money is just laundered through independent promoters. Artists will be loathe to jeopardize their industry contracts for this reason. Lack of exposure is death. Artists may regularly get screwed by their labels, but they fear the unknown devil of an alternative distribution channel may cut them off altogether. After all, Napster is truly democratic.

The only way to kill this beast is by attrition, because you can't cut off all the heads at once. The only thing to do is to build a whole new industry outsiide the current system. The pioneers in this area are going to go hungry for a while, so it will have to be done for the love of the music and for creative freedom. I'm cynical enough to doubt this will ever happen, but tyranny of the kind imposed by the RIAA always sparks a revolt sooner or later. Napster was just a riot with attendant looting.
