DVD Jon's Code In Sony Rootkit?

An anonymous reader writes "With some help from Sabre Security, Sebastian Porst and Matti Nikki have identified some stolen GPL'd code in Sony's rootkit. Ironically the code in question seems to be VLC's demux/mp4/drms.c -- the de-DRMS code which circumvents Apple's DRM, written by 'DVD' Jon Lech Johansen and Sam Hocevar."
