Now, this is an interesting thought! I have not considered this as a possibility before. It would make sense, as they appeared to want to recruit highly intelligent cryptographers, which would make total sense for Bitcoin development. They also seem to have disappeared AFAIK. I do think it is unlikely though, as the creator/group Behind Bitcoin is very likely someone from the cypherpunk group. But their identity should be kept a secret if they would like to be anonymous. Give them the respect they deserve for creating Bitcoin.
