Maybe I wasn't clear, but I was referring to "reproduce, edit, translate, distribute, publish or host this document" (cf. my remark on the squid proxy). IMHO, prohibiting "distributing" or "hosting" this document is just ridiculous in a world where there is an internet and has nothing to do with "ownership of the products of his intellect".
Further, the "products of his intellect" are themselves a partially reproduced, edited, or translated versions of documents his has read previously, in all likelihoods. I thought, every scientist (in particular, Mr. Hawking) is aware of this and thus claiming "ownership" of this "product" seems unfair. Hence, I find it bad taste.
Of course, we can now start to argue what does "edit", "reproduce" or "document" mean.
