Detailed article on how the Key2Audio protection racket works:
MacOPINION : Matthew Ruben | Celine Dion Killed My iMac!
Interesting conspiracy theory too:
...we see piracy continuing more or less undisturbed, with fair use being seriously disrupted.
It would be paranoid and silly to think that Sony and other record companies would want to destroy fair use just for the heck of it. There has to be a method to their madness, yes?
Key2Audio is the first step in a dreadful double perversion of Fair Use. The first perversion is the idea that by making a copy of music for yourself, you are depriving the copyright holder of the ability to obtain revenue from selling you additional copies of the same music. The second, linked, perversion is that by destroying your ability to exercise fair use, the record company extends its copyright power beyond the content (the music) to the delivery medium (the CD).
