More than a decade ago, when they abandoned desktop and regular users and only focused on enterprise, they made their biggest mistake. Where do you think Ubuntu Server users come from?
Absolutely true. RedHat desktop was awful (in comparison to other distros) for a while. Unfortunately, it's going that way again (Gnome 3). I only hope that someone will create a MATE repository for RHEL/CentOS 7.
What this implies is that the execs at RedHat don't eat their own dogfood, which is terrible for any software company. They should run RHEL on their personal desktops/laptops, etc..
