But with a very IBM move and with some tunnel vision, they got triggered by the few people who abuse RedHat license model and rugpulled everyone. More importantly universities, HPC/Research centers and other (mostly research) datacenters which were able to sew their own garments without effort.
Now we have Alma, which is a clone of CentOS stream, and Rocky which tries to be bug to bug compatible with RHEL. It's not a nice state.
They damaged their reputation, goodwill and most importantly the ecosystem severely just to earn some more monies, because number and monies matter more than everything else for IBM.
Remember. When you combine any company with IBM, you get IBM.
They are completely different products just reusing branding to confuse what people are asking for.
RHEL Developer is closer, as a no-support, no-cost version of RHEL, but you still have the deal with the licence song and dance.
CentOS gave folks a free version that let you run some dev environments that mostly mirrors prod, without worrying about licences or support. CentOS stream doesn't do this out of principle. It's upstream.
RHEL is the enterprise gold standard.
Fedora is a lot of the pipeline for it, which itself has become an incredible server and desktop platform.
All the work with Open shift, backstage, podman / qubelet, etc.
They're going to be fine, from my graybeard position.
Apart from that, in terms of keeping RHEL relevant, most of the attention is on making it easier to operate fleets at scale rather than the OS itself. Red Hat Insights, Image Builder, services in general, etc.
Those are the key things that would keep it competitive against Ubuntu, Debian, Alma, Oracle etc.
Of course I can’t speak for all the teams, but all new projects are going out on kubernetes and we don’t care about rhel at all, typically it’s alpine it Debian base images
