I think it goes with the territory. If someone creates something that ends up being used by millions of people around the world and it disrupts the age old financial, investment and banking sector in a way like never before then it is normal for people to want to know who was behind the project.

To what extent Satoshi wanted privacy is not known, nor why the name Satoshi Nakamoto was chosen nor how many people were involved in creating Bitcoin. Maybe the name was deliberately chosen for reasons we do not know yet.
