CentOS is ending being a repackaged but free as in beer RHEL clone to focus on CentOS Stream which will be positioned slightly ahead of RHEL releases: https://blog.centos.org/2020/12/future-is-centos-stream/
It seems there’s much end-user outcry on the mailing list about this (https://lists.centos.org/pipermail/centos/2020-December/thread.html#352168), but no one seems to be stepping up to fork what CentOS currently is and to continue developing it. There appears to be no good business model to sustain CentOS if the community won’t do it themselves (ala Debian).
It’s interesting to me that CentOS got as popular as it did. CentOS isn’t the same as RHEL and you can’t just call up Red Hat and ask to buy a support contract for CentOS (although I’m sure there’s a few small consulting shop who do offer such services). But Oracle and Canonical both DO offer to give you a free as in beer Linux distro with long term updates support and if you need it to easily buy a support contract for the distro you already have installed.
Why was CentOS so popular? Why hasn’t Oracle’s offering been more popular? Why don’t people appear to pay Canonical for support contracts?
