>Why does it matter? Why is that point relevant or being made?

It does matter, because as far as I tell, there’s been zero case the gov was after a person from non-Chinese roots. I’ve also seen similar cases in other countries like some south asians/arab countries, they are only after their own/previous citizens no matter what’s their nationality. Now you may ask why?! It’s simple, those are the most influential to the local public against the current regime than say a white guy lecturing Chinese people about freedom, he/she will never have the same impact than a local one who’s outside and away from any coercive or persuasive or any consequences.
