The story was called "fake" by some commentors on the Bitcoin Talk forum who demanded Mr Nakamoto carry out signed Bitcoin transactions to prove that he was the currency's originator.
As of the time of me posting this, no one has made any such demand on this forum.
Where does it say that part?
It's still meaningless mediababble. That one idiot said something dumb does not constitute news. After all, if Nakamoto doesn't want to talk about it (assuming he even really is Satoshi and not playing along for whatever reason), then why would he come out and publicly comment on something he obviously wants nothing to do with?
