The thing about Ughyurs is that there might be cultural repression that goes on in the area. There might even be instances of abuse and violence, one of the issues with even the best theoritical bureaucracies is that you still have to delegate tasks out and have some trust it won't be misused. There might be examples of low level officials who harassed a Ughyur family unfairly or put someone in remediation who wasn't an issue. It's more about the systems and overarching structure of the program that matters more.

This is the same logic we should be using with any nation realistically. And from what we see of Xianjang, there doesn't seem to be much actual strong evidence of systemic abuse. We don't see systemic evidence provided by the west, we don't see it in reactions by nearby nations, we don't see it by the actions of these supposed victims. So where is it beyond a bunch of claims?
