At the risk of opening up another debate I'd say that GitHub currently looks to be doing better (more releases, more enterprise sales) after Microsoft's purchase than before. I also see them as a model of how to keep a distinct culture alive and grow it inside a larger entity. If GitHub can do it I think Red Hat can too. But only time will tell. Everything at this stage is some form of speculation.
