Controlling the flow of knowledge through copyright restrictions.

Lawrence Lessig gives a lecture at CERN titled: The Architecture of Access to Scientific Knowledge

Really great talk on how the publishing world is only serving to add to the bankroll of a few at the expense of access to knowledge.

As an aside I LOVE the examples of remixing that Lessig consistently finds. The Breakfast Club/Phoenix remix series is really awesome.
