Do you really see this ultimately as an ethical question?
In it's current state, absolutely no doubt in my mind. Further down the line, who knows?
One other thing, music is one of the only products that could be subjected to this complete subversion of basic commercial practices & standards where businesses & individuals are expected to simply accept that technology has superceded honesty. If folk aren't willing to put something back into music for all the joy they receive from it then they can fuck off - that's not my solution by the way.
