Fedora Revenue?

Maybe there are aspects of RHEL they're not getting revenue from and maybe they'll find a way to close CentOS down (although I hope not), but Fedora? How could they realistically get revenue from Fedora? For a start, the quality and stability of the distro would have to improve dramatically - but that goes against Fedora's philosophy - even RH describes Fedora as "bleeding edge".

There's no way I'd pay money for a Fedora distro. Luckily, I know enough not to need to pay for support.
