What does "unauthenticated" even mean here? You aren't logged in, not logged in isn't a state of "unauthenticated", you haven't given any credentials meaning currently you don't have any authority, so unauthorized makes sense. You can have several sets of credentials and switch between them, not giving them any isn't being in an unauthenticated state its a different thing, and using "unauthorized" in that case makes sense.
That you're not logged in.

What? Yes it is.
> you haven't given any credentials meaning currently you don't have any authority, so unauthorized makes sense
Ok? Yes, if you are unauthenticated (and authentication is required), then you are also unauthorized. However, the error code is not communicating that you are unauthorized; it is communicating that you need to authenticate, thus unauthenticated is more appropriate.

That is exactly what being in an unauthenticated state means. What would you define to be an unauthenticated state otherwise?
