Article points out two things going for RHEL right now... a large patent portfolio (companies use these as sort of a mutuall assured destruction thing) and a much larger engineering pool capable of addressing distro bugs and issues without relying on "upstream" for everything.

You'll find that many of those engineers working for Red Hat are upstream or at least part of upstream for several core Linux tools. This is a great advantage since it means that changes they make have a much higher likelihood of making it into the upstream repo instead of as a maintained fork at the distro level.
