One big shop in the MAANG doesn't plan to switch from CentOS and doesn't care about Rocky or Alma. They recently completed a 7->8 migration. Alma and Rocky primary promises were 1:1 compatibility, 10 years of stability, and supposedly better governance. But when it comes down to it, CentOS is most often first with security updates. Cent(RHEL) pushed back the EOL once, effectively nixing one of the main claims of Alma and Rocky. Both appear to me to be just duplicating effort without specializing. If they're going to innovate, they ought to be 1:1 or something else entirely, not a 95% with a bunch of special case irregularities that opens pandora's can of worms support nightmare no one wants to support.
