Hmm, I've mixed feelings here.
Anybody who deliberately and knowingly breaches copyright with the express intent of either saving a bob or two on purchase price, or from profiting by republishing, is no different to me than any other thief. Good then, that there is a way of tracking them down, and good luck to those
who succeed in prosecutions against the file-sharing users in that category.
Conversely might it be the case that sometimes, as with patent trolls, copyright trolls emerge, who have no real interest in the breach, merely in the opportunity to profit from technical breaches, that might even have been accidental or unkowing?
