What the US govt seem to conveniently forget, however, is that many in the entertainment industry - particularly in the record side of things - actually SUPPORT so-called "illegal" sharing.
One example I can think of off the top of my head, is 'Fat Mike' Burkett, vocalist of the punk outfit NOFX and founder of Fat Wreck Chords. I don't know what the situation between him and the RIAA is at the mo, but he used to spend much of his time having FWC's name REMOVED from its books, only to find it readded in another guise ('Fat Records', 'Phat Records', etc). He's even taken the RIAA to court - and won - only to ding the C&D lasts for around a month or so before they're at it again!
He's issued several clear statements to the effect that FWC SUPPORTS file-sharing, as it's in-keeping with the punk ethos and exposes their artists' stuff to more people. He's even paid the court costs, fines and other associated fees of people convicted of 'illegal' downloading.
As as been already alluded to, piracy isn't killing music, the RIAA is killing music. I have limited resources, so I don't tend to buy albums anymore (not that I download them, I have Spotify) I'd rather pay for a gig ticket because most bands make feck-all from LP sales, it's touring that feeds and clothes 'em. Most of the bands I REALLY love most won't have heard of, which means that this disabled, workshy, scrounging, skiving pleb can afford to go see 'em.
Trouble with Spotify (and Pandora in the US) is that they DON'T pay artists properly, which is shooting themselves in the head, never mind the foot, as artists will soon withdraw their catalogues and then Spotify, Pandora et al will have feck-all to play! They receive something like 0.001c per play, so it's hardly a great revenue source.
Of course you've bands who think the mere mention of their name means they can charge a grand a ticket (not mentioning any names here, Mick, Ronnie, Keef). I saw tickets for Rod's last tour going (on ticket agent sites, not 3rd-party resellers, such as Viagogo) for £400 for the 'cheap' seats - and now that Macca has a new album out...
One day maybe the RIAA will ask the people it claims to represent before it starts stomping all over fans. Unless you know how the recording industry functions, there'll be a tendency to believe it's the BAND being an arse and, in 99.9% of cases, it never is, because most bands ain't greedy (unlike the 'One-Foot-In-The-Grave-Stones').
Okay, rant over, but I'm siding with Fong on this one...
