All authors of GPL software seriously need to play hardball with Red Hat/IBM and notify them of termination of license for breach of the GPL.

Something like: "You are blatantly and willfully violating both the spirit and the letter of the terms that govern my software, by adding additional terms and punishing the users downstream who redestribute it's source code. Stop shipping it immediately."

That would be bitchin'. If they continue shipping and ignore you, everybody sue them all at once; everyone who can, that is.
