Richard Stallman: A Free Digital Society (podcast)

"There are many threats to freedom in the digital society. They include massive surveillance, censorship, digital handcuffs, nonfree software that controls users, and the War on Sharing. Other threats come from use of web services. Finally, we have no positive right to do anything in the Internet; every activity is precarious, and can continue only as long as companies are willing to cooperate with it."
