If my company is in any way representative, then RedHat has nothing to fear from CentOS. Though a few of the engineers use CentOS as workstations or POC machines, our policy is that we have commercial support of our production software. We have run into issues with other applications that are no longer under support. CentOS has actually played a large role in getting RedHat into our environment. Without the ability to demo POCs, I think it would be unlikely that we would have tried Linux. (I of course am not speaking for my company in any way.)
