I think you underestimate the necessity for reliable support, especially in some sectors. E.g. for Telcos, where any outages must be fixed within specified (short) timescales in order to be allowed to sell telco service. It's less risk for a business to say we pay X per year, and if the shit hits the fan we can just pick up the phone. The other thing offered by RH is to say: here is a distro, we've tested it and can sign off on it being stable. That is also worth a lot in some sectors.
