Great talk by Jason Dixon given at the New York City BSDCON in 2008.
From the show notes on YouTube:
BSD vs GPL is a sweeping epic, focused on the dichotomy between good and evil. It peers inside the hearts and minds of the creators of these movements and dissects their battle for world domination. No common documentary will dare to follow the path that BSD vs GPL blazes. This presentation was given by Jason Dixon at the NYC BSD Conference at Columbia University on October 11, 2008
