I know the contribution to FOSS from Red Hat is great and all, but their product, RHEL, was a cancer for a modern software development.
Just easier to maintain for sysadmins doesn't make enough excuse for really long release cycle and the worst of all is they keep supporting the old products.
The result is a nightmare development environment for all the programmers who has to workaround the old bugs that was fixed years ago in the upstream but not fixed in the RHEL packages, but they have to use the RHEL packaged software for stupid sysadmin reasons.
