Instead of why are they not using, why would you use Fedora? In my view, because you want to be familiar with the ecosystem and potential future changes if you are supporting CentOS/RedHat but want newer features for your worknix. If the above isn't your use case, I would say Fedora has done some very nice bleeding edge stuff, so if you are the kind of person who likes Arch but doesn't like all the manual labor, Fedora might be up your alley. I do know that I was very impressed with Fedora on my Macbook Pro 2014, until I realized that the proprietary video drivers refused to work in UEFI/BIOS mode. A deal breaker because I'm working on Unreal Engine 4 linux native editor, otherwise I probably would be using it. edit: Also, I installed both latest stable and beta (22 I think), and some of the issues related to the rawhide packaging production cycle, so I plan on trying it again once 22 is out and/or when the repos are updated for it.
