RH fell behind the times. Their paradigm of a stable though an older kernel was suitable for the times when kernel wasn't that stable and things in the industry were developed slower than today. I work in a big enterprise space and usually we do Ubuntu if we can and SUSE Enterprise if we can't :), i recently tried Docker/Kubernetes on a recent RHEL - looking at the kernel version i already didn't expect the stuff to work and of course it didnt work (no complete namespaces features support). Their push for their own custom software platform instead is a good match for IBM.
