The entire conversation around the Uyghur "Genocide" has never been serious. The claim of genocide came from the estimated rate of population growth reducing(to a still positive rate) and the actual report, written by a high up member of the Victims of Communism Memorial Foundation specifically used the phrase "Cultural Genocide".
Additionally, the region was a focus in the early 2000s during the War on Terror, when China asked to include the extremist groups in terror watch lists. The US agreed and they were included up until a couple years prior to the events in Xinjiang.
These were essentially re-education camps focused on radicalized groups. If anything, it's a more productive path than similar efforts, ie the ex-ISIS camps in Syria.
Those never seem to be mentioned in tandem. They're supported nominally by western countries, where ex-isis members and families are kept indefinitely. Thousands of stateless prisoners, including women with children are kept there. When the boys reach the age of 14(iirc), they're put in the actual prisons with the men. Those camps essentially concentrate the extremism for the eventuality of the camps' closure. No attempts were made for deradicalization.
