That's the marketplace of ideas in action. Volunteer-run distributions like Debian and Arch have switched over. If the whole world where RHEL, you might have a point, but it's not.
You can contribute to your own distro, and the "veteran UNIX admins" made Devuan. If it still counts as obscure and you don't want it to be, you - yes, you - can do something about it.
The free/open-source community is a do-ocracy. The things that are worked on are the things the people doing the work want to work on. If you have a well-paid sysadmin job where you are providing your employer value by using the work they provide you for free - and, in particular, using their ongoing work which they continuously provide you for free, because you feel like a mainstream distro from 2014 doesn't suit your needs - then you can either be grateful for what you get for free or you can contribute back.
(Which doesn't necessarily have to be contributing your own work. I'm sure if you get your employer to donate one FTE's salary to Devuan, you can change its obscurity pretty quickly!)
