I was curious why CERN and Fermilab chose AlmaLinux instead of Rocky Linux. After googling, I found out that the Rocky Enterprise Software Foundation, which controls Rocky Linux, is a public-benefit corporation. This is a for-profit type of corporation, unlike what the name suggests. The AlmaLinux OS Foundation is a 501(c)(6) non-profit, which in my mind is clearly the type of organization that should control such an OS.
