Incorrect, according to their FAQ[0] and the original article I linked[1]:
> What does ABI/binary compatible with RHEL mean?
> In July of 2023, we announced (opens new window) that we were shifting our goal from being a downstream rebuild of RHEL to maintaining ABI compatibility with RHEL. For the AlmaLinux team that means that everything from software applications to kernel modules that work on RHEL will work on AlmaLinux, and if they don't we would consider that a bug.
TL;DR: they are using CentOS Stream as their upstream.
EDIT: Sorry, you're correct -- I was thinking you meant their original goal of "bug-for-bug" compatibility with RHEL.
