Most copyright laws make a distinction between copyright infringement done as part of trade and copyright infringement done for personal use.
EDIT: For fuck's sake, this is true, and follows from WIPO Copyright Treaty into the Copyright Directive for the EU and whatever the US equivalent is. Breaching copyright as part of trade turns it into a criminal offence, merely breaching copyright for personal use is a civil tort.
That's why in the various bit-torrent legal cases people who torrent are sued for loss by companies in courts, while people who run businesses running torrent sites are prosecuted by law enforcement.
