Ours is less and less a free society

Very interesting animated presentation by Lawrence Lessig (Professor of Law at Stanford Law School) that builds on this refrain:

1. Creativity and innovation always builds on the past.
   
2. The past always tries to control the creativity that builds on it.
   
3. Free societies enable the future by limiting the past
   
4. Ours is less and less a free society

Unfortunately the audio stopped on me half-way but still worth it. Lots of historical examples. It's aimed at supporting Open Source and certainly provides food for thought.
