I history commercialisation of intellectual property is a recent invention. Prior to the invention of recording and distribution media living musicians would have to perform to make an income. Not too much earlier there wasn't even an opportunity to make a buck from sheet music. With digital distribution one may just as well see it as a return to basics through sharing, as theft. Societies are still struggling to make up their opinion on which definition to support. The recording industry has a lot of influence through their wealth, but it is far from clear that the industry's bare existence is to the best of society.
The idea behind the KPA was to create a community, not a commercial platform. I think this is best for the long term.
Btw, I fully respect the integrity of commercial products whether it is KPA-profiles or other music produces, but I prefer the community approach that pre-dates the commercial music industry when given a choice.
