This article talks about Sony's Digital Rights Management (DRM) software that comes on Sony music CDs. The DRM works in part by installing a bunch of secret software on your PC, without your permission! In other contexts we call that computer trespass and/or illegal behavior.
This is just one more example of a long term trend in the music industry to treat customers--all their customers--as thieves, even in the absence of evidence. It's no wonder CD sales are down--who wants a music CD that takes over your computer, installs secret software, and changes your working environment in unpublished ways?
