Londo nailed it. The writing is public, the talks aren't supposed to be, and this one especially so. You can record a convention for your sick wife to be able to benefit, but they made no such allowance in their "no recordings" disclaimer. This time they went to great detail in the disclaimer and even forbade sharing your notes with anyone.
As for the clear circular logic (that boils down to - it's not my oppinion, for proof look at my oppinion written under a pseudonym!) I don't think many noticed. The JWs are trained to view the WT magazine as being on the same level as the bible, as if it's from god himself. So instead of seeing a man quoting from his own writings, they see a man quoting god.
