I think that what Kazaa stood for was against some law somewhere, and of course that aspect of it needs to be addressed, but as one who has actually touched into the music business, I can assure you that no one, absolutely NO ONE, lost any money. Companies and artists might not have earned as much as they would have otherwise, but lost money? Not a cent.
Even people on the very low end of the totem pole make incredible amounts of money in the music business.
So, from the standpoint of Law, I have to agree with things like this, but I don't feel an ounce of sorrow for some artist who earns $3 million a year in royalties and points instead of $4 million. Again, the Law gives them the right to that $4 million and they should have it, but only because of the law, not them simpering over their greed.
