Most of them didn't even try to support stream. I'm not sure what the process behind that was.
CentOS was free, which is why we used it. Sure, our SAP boxes run RHEL but the other stuff doesn't. We started moving a lot of stuff to Ubuntu as well.
Now, Ubuntu is by no means perfect, snaps are annoying, etc. But Red Hat really angers me with their decisions during the last few years.
One example is removing OpenLDAP:
The openldap-servers package was removed in Red Hat Enterprise Linux 8. The openldap-clients package is still shipped though.
If you use openldap-servers in Red Hat Enterprise Linux 7 (RHEL7), you need to consider to change your LDAP server from OpenLDAP to Red Hat Directory Server (RHDS) in Red Hat Enterprise Linux 8 (RHEL8).
RHDS is provided as an add-on subscription in RHEL8, so you need buy the subscriptions in addition to RHEL subscription.

Additionally, Red Hat support is so bad these days. It almost reminds me of Microsoft Technet forums of the past. Random 'techs' offering copy-paste solutions and the same bad information.
