If you are referring to the question from the IRC chat, I think it was not about silencing but rather about genuine interest in further reading material since he didn't yet publish on anything from his three CCC talks. Some parts make quite sophisticated points so it would be really helpful if it was elaborated in written form.
Every year a brilliant talk by Joscha- if it weren't for the scared by the Results of Science Radicals trying to censor at the QA.
