Can't tell you how many time government and military refused to pay less for our product running on CentOS and instead wanted to pay lots more for a Redhat license so they can have support. Nevermind that once setup they only have to do yum update to get the latest security patches and not much else.

There are some companies that offer CentOS support but they are not as prominent perhaps. I think Oracle should have done that, and in the process win some brownie points with the OS community.

From their point of view pissing off some idealistic OS nerds wearing T-shirts and flip-flops is nothing to worry about. However, the problem is a lot of these nerds end up making technology choices, directly or indirectly by advising their managers what is better, etc.
