Satoshi did the only right thing he could do, he moved Bitcoin away from any connection to one man (himself), because he knew that was the only way his project would succeed. In his email to Mike Hearn he clearly says
“I’ve moved on to other things. It’s in good hands with Gavin and everyone.” Reading the correspondence between Satoshi and Gavin, it can be concluded that Gavin was not very satisfied with the way the project developed. It may not mean anything, but even then some people didn't like the fact that Satoshi was the one who actually had the last word on everything. In a way, Satoshi left the whole project to them, and some were certainly not too sad about it.
gavinandresen: I just wish I could convince [Satoshi] to switch to a more collaborative development model. Tritonio: what do you mean? what is the current development model? jgarzik: mostly-closed. open source, closed development. gavinandresen: Satoshi is the gatekeeper right now, all code flows through him.
Worth the read.
A very good article with a lot of links that tell the story of how Bitcoin evolved in its early days and the relationship between Satoshi and those who worked on the project with him.
