Reading the histories of both companies, it seems to me that Redhat was always IBM. The acquisition was a marriage of separated twins more than anything else, the dominating culture in both organizations is largely sales and consulting driven, with public strategy not quite identical but strongly rhyming. The technology aspects (while perhaps once important) were far from the prime focus of either organization long prior to the merger. I think of IBM's acquisition more as a desire to access marketing expertise and established sales channels than anything to do with technologies, most of RH's open source technology is after all mostly just an advanced form of disguised marketing

The only question I have is, what grant application(s) is the survey data being used to support?
