Hmmm. To bikeshed a bit about the term sponsor - I admittedly wouldn't be able to come up with a better word but feel that this one is wrong. Maybe it's my lack of English language skills but it seems to me a sponsor should SPONSOR what is going on, not dictate it. I see SUSE as a community member of the openSUSE community - and although the roles are slightly different due to Fedora being a rather different community, I think Red Hat has a roughly similar position in Fedora.
In any case, using the term 'sponsor' or not, Fedora is a community. Not a community-led distro like Debian, Gentoo or openSUSE, but neither is it a closed development thing like RHEL and SLE are. So THAT word, community distribution - fine.
