I work as a Linux sysadmin for a university, we’re paying for a full RedHat site license with all the goodies, and we certainly feel royally screwed over by this.
Not every single piece of software we run is a RedHat developed/sanctioned thing, and the removal of a guaranteed bug-compatible development platform for the people building those pieces of software - without jumping through hoops or limiting development efficiency - mean that we can no longer guarantee that core pieces of our infrastructure software will remain available for our RHEL installs. Not to mention course IT, where things are even worse in that regard. Lots of such software is already developed/tested/packaged on Alma/Rocky, and if they start diverging from being RHEL bug-compatible - which is very likely with this change - then we’re going to either have to switch away from RHEL - and the paid support, or lose support from the pieces of software.
We’re probably going to have to move a bunch more of our ~1.4k systems off of RHEL and onto things like SUSE, Debian, etc in the near future, just so that we’re ready for when shit really hit the fan.
