Hi
You forget the presence of various other projects such as Legacy, Documentation, Websites, Infrastructure etc...
Are they provided by RH? RH provides some of the servers, yes. But the contents? Most probably written and provided by volunteers from the community to the community. I.e. direction: Community => community.
Oh btw I have reviewed documentation, contribution to release notes, contribute to legacy (legacy is chaired by Fedora Core release maintainer) , contributed to websites and infrastructure team both of which has other Red Hat people working on it. Fedora Documentation Steering Committee is chaired by Red Hat. Red Hat has been team members of all these projects. So try and understand the processes and people involved better. Its all documented in the wiki @ http://fedoraproject.org/wiki/Projects
