@clacke @smxi The GPL does not have any clause that makes a user entitled to any future versions or any tech support.
Therefore, it is not a violation of the GPL to terminate business relationship based on an action that is allowed by the license but not allowed by the business agreement.
Red Hat can't come and take away the code they already gave you, and can't stop you redistributing it. They have all the rights to not talk to you any more though.
