It isn't quite correct that RedHat is saying that, IIRC from the LWN discussions, the clause is about giving someone who doesn't have a subscription the benefits they would have if they had a subscription. So it would be fine to redistribute in some cases but not others. Probably fine to redistribute every update to entities who already have a subscription, or to redistribute one package to a contractor working on fixing a bug for you etc.
