A Presentation to Introduce Linux: "Honestly, I don’t believe in copyrights and licence notices. Humans don’t need them. Licences tend to enslave users, and act like rigid policemen. Copyrights totally cripple the usability and enhancement of the presentation (or for that matter, anything): if you can’t modify it or distribute it, what are you going to do with it? Keep watching with popcorn, again and again?
Hence, you can freely modify this show, distribute it (in part or full) to all your friends, run it in an expo or at a conference, and use it however you want. We are all humans, and I don’t like to impose conditions and be a bully."
