This seems to be an old article (January 7, 2014) anyone know if Facebook still use Mercurial? About securing different parts of the repo, the mercurial server actually doesn't have any user authentication! You are meant to do that yourself with SSH or a web server, where you should be able to have more restrict access to some special folders. About using a single repo, it does make sense to have all code that interact with each other at the same place. Imagine changing a variable name in some API and at the same time update all usage of that name in the whole codebase. And imagine the bureaucracy and people management for just making a variable change if there where separate repos witch you might not even have access to.
