Richard Stallmann erklärt in unter 15 Minuten die Bedeutung und den Sinn von Freier Software:

It is the first TEDx talk of the founder of Free Software movement. Stallman, RMS for short, has changed the world with his vision of freedom for the digital age. He launched the GNU operating system, used with Linux as a component, and inspired the development of Creative Commons licences and Wikipedia project. In this talk, Stallman describes how nonfree programs give companies control of their users and what users can do in order to recover control over their computing.

Den Vortrag gibt es hier auch als WebM.
