It doesn't feel any less moral than someone dictating what art I should or shouldn't enjoy. Yes, there's a greater weight placed on someone's opinion if they're the ones that made the art, but in the end, if I buy a CD of music or a print of an artwork, it would be a ludicrous proposition that the artist should demand that I stop listening to it or looking at it.

Yes, I would definitely give more credence to the artist who produced it saying "This work was trite crap, and I disassociate myself from it" than from a music critic saying "this work was trite crap, and you shouldn't waste any more brainpower on it", but either is very marginal- sometimes any art that is very much a product of it's time has reason for a second life, possibly a Renaissance; history doesn't repeat but it has a tendency to rhyme.
