The specs themselves usually come from Fedora first, where they are MIT by default (per Contributor Agreement, at least). So RH can do anything they please as long as they acknowledge the authors (which is done trivially by not mucking with %changelog). Anything they please likely includes terminating your account if they sniff you using it to avoid the fees or enabling others to do so. If you are contemplating, say, using a Red Hat Individual Developer Access (or what they call it) to redistribute the sources, they have a provision in the terms you have to agree to just against such cases.
