The encryption system used to control the content on hd-dvds is an AES based publickey system. This is one of the public keys assigned to a player, allowing that player to play the content. It had to be brutally ripped from the memory of a running program, because they want to keep the children safe from pirated movies.
Some people posted it, and the MPAA/AACS group immediately sent DMCA 'takedown' notices ordering people to take down this (a hexidecimal representation of a number).
Also, I am not personally profiting from this work, it does not cause undue damages, it is an artistic interpretation of the current maelstrom of internet activity. Their mark is covered under trademark law, which has exceptions for parody and artistic expression (guess what this is). The code is covered under the DMCA, which is bullsh*t because it's a number.
Also, c*cks.
Instead of just a text repost of the number, this is a piece of copylefted art (the sound is too). This is a defensible presentation - basically, they can't issue a takedown on it.
I support spreading the number for a few reasons. The way the key system is structured it won't matter in a few months as far as encryption, but it's the fact that they were trying to get it pulled with the DMCA that bothers me. They need to learn that they can't control numbers, and that the collective intellectual property laws of various countries can never silence our innate rights.
