If you are referring to reptilia he has no leadership role with Monero. He runs the MEW group he started and is essentially a user group, but other than that he is just a user like anyone else (though certainly a vocal and opinionated one, for better or worse).
Seriously, ROFL
rpietila IS Monero
You are confused. Monero is an open source project i.e. https://github.com/monero-project. rpietila doesn't even have access to the repo, nor would he have any idea what to do with it if he did. (Nor does he have access to any of the other project assets, such as the 'monero' btct user, web site, domain names, etc.)
He's a user and self-appointed promoter.
If Mark Karpeles shows up here and starts telling everyone who he can get to listen to him how great Frappuchinos are, and how anyone and everyone should start drinking five Frappuccinos per day, that does not make him Starbucks, or a leader of Starbucks, or a spokesman for Starbucks.
