Yes, that’s the biggest and probably most valid criticism not tied to the film’s writing or acting. It’s pure white savior narrative. Same issue with Last of the Mohicans and a bunch of other movies.

This is all just blatantly, completely untrue. I’m gonna go ahead and do the thing I initially told myself I wasn’t, but you’re so off base I literally have to: do you have any source, at all, that backs up any of what you’re saying? Any specific piece of Star Wars media one could look at to verify that what you are describing is at least even close to accurate? Because I’ve literally read dozens of Star Wars novels and graphic novels, have played most Star Wars video games, and seen most of the Star Wars television series ever created, and at no point have I ever encountered anything that supports what you’re describing.

Well, the books were never really “canonical” in the same sense as the films. But the films themselves, if that’s what you’re going on, never make any reference to Vader’s presence in the empire in a larger context. We just see that he is, generally speaking, the person in charge, aside from Tarkin in A New Hope, and the Emperor in Return of the Jedi. So, if we are going purely off of that, then we have no way of knowing how various parties in the galaxy perceived Vader or understood his role in the grand scheme of things. Which is probably fine, because it’s fundamentally unimportant to the story being told. But it still makes more sense for him to just be an agent of the Emperor who operates with virtually unlimited authority and who is outside of any kind of formal military command structure.
