Overly optimistic?
"In other words, to get to the "sharing culture" they advocate, no group has to lose out, nobody need get poorer, and certainly, nobody has to have their rights taken away. To argue otherwise is pure, childish spite."
But surely, the "sharing culture" they advocate won't have room for record companies - who are content owners, not creators - to stand between the producer and consumer taking the lions share of the transaction.
Without them being the gatekeepers to the promotion/distribution networks or being the only people who can produce a professional quality recordings, there's no justification for them taking as much money.
