You are missing the point completely. He tried selling support and failed miserably, he made no money. So, he issued a better version of the same software under a commercial license, and that sold well. RedHat does not do that. Everything they do is available in CentOS, or is available freely. They make money selling support. It's pretty obviously not a valid analogy.
