If RH never made another release, there would be similar disruption.
That doom theorycrafting is irrelevant to my question.
> RH *is* a business, Debian is a community effort
That's also irrelevant. They are distros from a business standpoint. CentOS being interchangeable with Fedora since forever. How they came to be is a footnote.
My question was about relative usage and some way to measure that metric other than guesswork, as a challenge to the assertion that RH is "a marginal player". systemd adoption in RH is mentioned in 100% of the "discussions" on the topic. So someone here is showing bias.
If you were going to address the issue in an objective manner, you might note Debian, tends to identify itself when you run fingerprinting on servers (e.g. Apache and Nginx). Debian tends to be the most common identifier! Nobody believes the bulk of the responses (with no OS identifiers) are all non-RH (some will be slack, some debian, some gentoo, whatever), so that's an interesting metric that isn't definitive.
I think I understood completely. Attempting to derail into some form of "RH can be replaced" discussion, is of no interest to me.
This discussion didn't seem to pan out any better than previous attempts to verify that there is a more prolific distro.
Calling RH a marginal player is simply disingenuous, as of today.
