That’s a post about a different CD copy restriction scheme. The one with the rootkit like behavior is by First 4 Internet in the UK (the UK has evil software companies too :p). A different beast and style of CD copy restrition.
I did mention the Sony rootkit-like software in the thread about removing screws. That thread morphed into a discussion about MP3 players and iPods and then a post about the evil Sony software. My post about the Sony software and my rant about copy protection and DRM on CDs.
