Imagine if you'd written a game and you put it on iTunes, and you'd observed 150MM downloads, but only got 11 pounds from iTunes. You're telling me you wouldn't feel exploited?
There really is a double-standard at work here. When musicians/songwriters say they're being fleeced, members of this (hacker) community pooh-pooh them, and accuse them of being dinosaurs who just don't get it. When a developer writes an app that gets rejected by the iTunes store, devs are up in arms about lost dev time and the financial implication. Similarly if Google Checkout decides to terminate a developers account and said developer loses pending income.
It's totally natural for groups to look after their own, but one might have hoped that an elite community like Hacker News would be able to recognize this tendency. Sadly, from the evidence I've seen here from posters, whose views on the music industry are, generally speaking, at once flippant, condescending, arrogant, cold-hearted, and ill-informed, this is far from being the case.
