Different Red Hat employee here, that said, this opinion is my own and I have no real authority to say anything beyond my experience. I, in my job, have a lot of contact with IBM folks now for obvious reasons, but I think it's a slow Red washing rather than the other way around. The independence of Red Hat is fiercely defended and is largely respected, even by IBM. I think we all want this to work as it is, rather than make huge changes, especially culturally.
