One of the old theories out there was that satoshi was a group of people and not just one person. I think it's much more compelling argument that Wright may just be one member of that group. But, why claim that you are satoshi after all this time is lost on me.
You've got to realize that Craig's "admissions" are old leaked data. NOT statement HE is making now. He's not claimed to be Satoshi in any public fashion that was intentional.
And statements he has made are pretty clear that he acknowledges "the team" but that "the team" identity is sacrosanct - something that he sincerely hoped for himself.
Here's what has most likely happened. Craig got hacked by a disgruntled ex team member, or someone on the fringe of the team. They were pissed and attempted blackmail/extortion. The "fake" stuff was probably planted by Craig/Team in order to taint the breach of security.
It has half worked, and half not. It HAS worked to the extent that their is still anonymity at some level for a time. I mean, there isn't global 99% concensus - with which media coverage would be millions of times worse by now. You'd have the whole paparazzi effect in hyper drive by now.
AND it is important to understand that it is quite possible that you're only seeing a snapshot in time of Craig = Satoshi. For all you know Kleinman could have taken a turn(s) (would explain most posting times in U.S. for example)
I think that Craig was possibly the "designated Satoshi" by concensus most/all of the time.
