There are a ton of perfectly good Linux distros out there--many with some type of support available. The thing with CentOS was that, especially latterly after the CentOS team was acquired by Red Hat, many saw CentOS--as a downstream rebuild from RHEL sources, albeit with a different build system--as a semi-supported version of RHEL for free.

For people who don't want CentOS Stream, i.e. basically the nightly RHEL builds, the lack of having a versioned CentOS mirroring RHEL versions coming out of Red Hat (for about the last 10 years) puts them in somewhat uncharted waters even if they could pick one of the RHEL alternatives and "probably" be fine.
