Why There Will Never Be Another RedHat: The Economics of Open Source (2014)
I feel that there is an inherent conflict of interest in the OSS support sales model. Hypothetically, if your software were really simple and robust (think standard unix utilities), nobody would pay for support. On the other end, if you have to deploy openstack, kubernetes, or any other stack with a lot of moving parts, you need support and personnel. So in a perverse way, it's in your interest to make complicated shit. In reality, it is perhaps not quite as bad, but I definitely feel that with a lot of projects for which RH is the sole upstream, the quality or elegance isn't quite there when compared to more traditional linux or unixy things which have more diverse upstreams. This manifests in systemd, freeipa, glusterfs etc. too. These are generally hard problems though. So it's not quite black and white.
