BoingBoing is not a high quality commentary site to begin with and Cory Doctorow is an idiot. He's a fanboy of the worst type (Apple (prior to this), kitsch, anti-DRM) and happily bends reality to fit his view of things. Listening to him for advice on computers is like listening to the typical RedState poster on political matters.

The Ars article (http://arstechnica.com/journals/apple.ars/2008/11/17/apple-brings-hdcp-to-a-new-aluminum-macbook-near-you) is much more reasonable about it.
