His idea to bar linking to copyrighted materials is absurd and could break the web, almost everything on the web is copyrighted by someone. How exactly would implement this for pages where there are multiple copyright owners for different parts of the page, who have only given permission to the original site to use them? Would I need every commenter's permission to link to a Slashdot comment page? You only give permission to Slashdot to use your content not me.
There are already ways to restrict people from linking to your site, you could block all requests that don't have a referer from a list of approved sites. I realize that it is easy to turn off or fake referers but most users either won't know how or won't bother. Also as for restricting copyrighted material to only preapproved individuals, that technology already exists and is used very widely on the internet and copyright law can already deal with sites that will take copyrighted material and simply redisplay it. While I share his desire to see newspapers continue and not die out, this is not the right approach (or at least we don't need new laws for them).
