How many times have you been to Xinjiang? I’ve only been once, and didn’t notice any credits scoring going on even among Uighurs. I get that something bad must be going on sometimes, and maybe north Xinjiang (more populated, more Han) is a lot different from south Xinjiang (more Uighur), but if you visited Urumqi or Kashgar tomorrow, or even lived there, you probably wouldn’t notice much.
