Earlier quoted context omitted.
I'm trusting Carl George's words here: https://old.reddit.com/r/redhat/comments/14jq5i7/red_hats_co... Those Rocky Linux repos are either not code (website, wiki, etc.), and a few are tools for repackaging/rebranding an existing Linux distro's source code bug-for-bug - an activity which, by definition , does not and cannot offer anything more than the original code already did.
If I'm reading that reddit comment correctly it referred to contributions to RHEL not contributions to open source, which if I'm reading it correctly was what your original comment stated. It seems that Rocky Linux have contributed code as open source, just not directly to RHEL.
not migrate2rocky, or almalinux-deploy. But if you look closely, they are mostly 'infrastructure' tooling to sync sources or deal with build nodes.
