It's an article by an ethnic Uyghur suggesting, in response to other articles, that if you love the country of China then we should also be working to consciously use the language in public to help elevate the perceived status of the Uyghur population in China.

It seems like it's mostly referring to public officials as well...

I don't know exactly how I feel about that as I don't even kind of have the cultural awareness and context, but it seems like an opinion piece and has nothing to do with "not allowing them to speak their own language" any more than the cultural faux pas similar to Spanish speakers in the US.
