Native speaker valorization?

[pauamma]

I came across https://twitter.com/ervinmalakaj/status/1230855895179022338 and I'm wondering: is that tweet referring to the same principle that says (paraphrased) "for questions of language usage correctness, always defer to native speakers' knowledge of their language"? If so, how does that critique deal with the opposite tendency (I'm not sure whether to call it neocolonialism or cultural imperialism) to mock native speakers of non-Western cultures based on misunderstandings of how their language works, saying in effect "they're not even able to speak their own language properly"?
