It's just typical of the music industry's attitude to copyright protection...
...if you are unsuccessful in your attempts to get the pirates, then hit the innocent bystanders with a shotgun blast of law suits. "Collateral damage" and "friendly fire or blue-on-blue" are not restricted to the American military efforts !!
And they wonder why people are not more friendly and/or helpful towards them !! If they stop behaving like Nazi thugs, maybe people might be more forthcoming in their efforts to help fight against piracy.
I love reading the free books/chapters published by Baen Books. Then I go out and buy the books/whole series (paper version). I don't go round pirating e-books !! If I think my friends would like certain books, I will also buy copies for them to read !! Authors have to eat too !!
This is the equivalent of Indie music published on the net, bypassing the Almighty Music Industry.
