This boycotting is not limited to consumers. Various celebrities are doing it too. They have terminated their contracts with western clothing brands.
Interestingly, one such celebrity is Dilraba Dilmurat, a Uyghur celebrity who's very famous in China. Her company announced that they're terminating their contract with Adidas.
In addition, many Chinese companies have doubled down and proclaimed that they "support Xinjiang cotton".
Various people have pointed out that they do not believe the forced labor stories, because over 70% of cotton in Xinjiang is picked by machines. Whether you believe this statistic is up to you — I'm simply saying that this statistic has been mentioned.
This comment is in no way meant to endorse, nor to criticize, the Xinjiang situation. I am only commenting on the facts surrounding the boycott by Chinese people.
