We can also take a look at the linux kernel that powers the docker instances and faint in terror.

These “moving parts” are implementation details which (iiuc) require no maintenance apart from backing up via some obvious solutions. Didn’t they make docker to stop worrying about exactly this?

And you don’t need multiple roles, specialists or competences for that, it’s a one-time task for a single sysop who can google and read man. These management-spoiled ideas will hire one guy for every explicitly named thing. Tell them you’re using echo and printf and they rush to search for an output-ops team.

These moving parts require active understanding and maintenance, as they will change on each and every upgrade, which also requires manual upgrade steps and potential debugging on breaking changes. OCI images let you worry less about dependencies, but what they don't eliminate is debugging and/or upgrading k8s configuration manifests (which we are looking at here).

Sure, and computers are rocks powered by lightning - very, very frighting. That doesn't invalidate criticism about the usability and design of this very product my friend.

Maybe they won’t change or migrations will be backwards-compatible. We don’t know that in general. Pretty sure all the software installed on my PC uses numerous databases. But somehow I never upgraded them manually. I find the root position overdefensive at best.

If it were a specific criticism, fine. But it uses lots of assumptions as far as I can tell, cause it references no mds, configs, migrations, etc. It only projects a general idea about issues someone had at their org in some situation. This whole “moving parts” idiom is management speak. You either see a specific problem with a specific setup, or have to look inside to see it. Everything else is fortune telling.
