That's actually not what I was referring to.

First of all, RedHat now belongs to IBM, and they've never been shy about squeezing customers for a buck.

Second, having dealt with their support, it's hit or miss to get a somebody helpful or an endless cycle of tickets. Patching and versioning is sometimes a complete mess.This especially sucks as the main reason most organizations go with RH versus others is for patching and support.

There's also a lot of things where there's a RH-specific implementation , which is further distancing fun other Linuxes and often ignores standard ways of configuring things.

RedHat actually benefitted from Fedora, CentOS etc as it allowed the community to develop products in a way that could be tested to be reasonably compatible, and to develop our port back fixes etc. It wasn't just "RedHat made this and others just took it" but in many ways a symbiotic relationship. Yeah some orgs just went with CentOS but often it was those who worked on RH corporately would run CentOS at home in order to have a similar environment.
