I think scardeypants has it; downloading is not illlegal, I understand (in a similar way that listening to an illegally broadcast radio station isn’t), but uploading is.
An interesting article.
Seems that an increasing number of people are getting letters about ‘illegally downloading copyrighted material’. I suspect that the IPs are simply registering that people are using torrent sites, and passing that information on. The ‘music industry’ is probably paying the IPs a nice little sum, so that they can get hold of people to sue them.
Theft? Theft? Charging money for most of the shite that’s out there atm, that’s theft…
