Linkbait title. TLDR: Wikipedia needs more images, videos etc. In a bid to rile up emotion he compares wikipedia unfavourably to an ancient version of encarta. AFAIK: there are no technical restrictions on adding videos and images to the pages. The reason there aren't more videos/images etc is because of copyright concerns. It just isn't that easy still to find images/videos with clear copyright. Since text is literally created by the authors, wikipedia automatically assigns themselves the right to use the text you type in on.
