Ubuntu is already the default for people with ML pipelines and more and more vendors are targeting Ubuntu first for their software.
CentOS will be effectively dead for a lot of companies starting next year (or 2024). (At least we aren't planning on licensing 10^5 systems on RHEL...). I imagine for those same companies, RHEL isn't far behind it.
What's even worse here is that at least for us there are some things that we pay for RHEL for. If we switch all of our other servers, those RHEL licenses won't be continuing either.
Obvious, but stupid.
Ubuntu followed Red-Hat's footsteps away from desktop into the server room, as there is no money to be done there, and it will follow it still, if there is still not enough money on the server.
Canonical and RedHat are paying the salaries of the people steering the direction of Linux as a whole. They're forcing you to choose between the two.
That's pretty weak sauce even compared to the five years Debian and Ubuntu offer. And Debian actually supports all their packages, unlike Ubuntu which tricks people into installing unpatched garbage from 'universe'
What happens in practice with this sort of "rolling release" is users end up patching endlessly in production, which no sane person or organization would ever want to do. This was the exact situation for another Redhat acquisition for years now. JBoss EAP and community editions (wildfly now I suppose), everyone who could moved off of JBoss long ago.
