The Chinese government will freely admit to you that Han chauvinism towards ethnic minorities is still a problem to some degree at all levels of Chinese society. They would also tell you that their path of economic development since the beginning of the reform & opening up period has caused the the western, interior provinces to lag behind in development (of which the Xinjiang Autonomous Region is one of them and both problems are ones where coordinated active efforts are being taken to resolve)
However, there is a VERY VERY big difference between “China has not yet achieved ethnic harmony or a countrywide equal level of economic development” and “The Chinese government is enacting a coordinated campaign to exterminate the Uyghur people”.
I know there are some people in this subreddit who have like Google docs of articles & can provide some context on other details (I can too if you have a specific question) but this is the prism through which you should (in my opinion) be looking at the situation.
