Adding insult to injury: After releasing a stealth DRM application that has spawned a new series of exploits, there are now reports that parts of the Sony Rootkit DRM were built on top of the LAME encoder, which is open source technology.
In the "I can't make up stuff like this department", Sony actually said that the rootkit was
...an important tool to protect our intellectual property rights and those of our artists.
One might conclude that it is important for Sony to protect their IP, and only their IP. Too bad the LAME encoder is LGPL -- if only Sony had taken the time to read my post on Open Source Licenses and Intellectual Property.
