A non-profit called the Open Enterprise Linux Association (OpenELA) has been formed by Oracle, SUSE, CIQ, and other organizations that make Red Hat Enterprise Linux (RHEL) and CentOS rebuilds.
So far they’re promising to “establish and make accessible the sources, tooling, and assets to all members, collaborators, and the open source Enterprise Linux distribution developers to create and maintain 1:1 downstream derivatives of EL.”
CIQ is the company behind Rocky and they joined. I believe Alma is taking a slightly different approach than the others, hence they did not join.
