Hiding Satoshi himself was referring to someone who does not want the world to know who he is. Tor has used a lot of ways to protect his IP addresses. His mastery of the English language and his use of a fake name will make it difficult to know his identity.
why do you need to know who he is? Many people do not use Bitcoin not because it is unknown, but rather because it led to speculation with high volatility, most of them do not know who is Satoshi and therefore do not care about that.
