Viewers of some of China’s most popular online variety shows were recently greeted by a curious sight: a blur of pixels obscuring the brands on sneakers and T-shirts worn by contestants.

As far as viewers could tell, the censored apparel showed no hints of obscenity or indecency. Instead, the problem lay with the foreign brands that made them.

Since late March, streaming platforms in China have diligently censored the logos and symbols of brands like Adidas that adorn contestants performing dance, singing and standup-comedy routines. The phenomenon followed a feud between the government and big-name international companies that said they would avoid using cotton produced in the western Chinese region of Xinjiang, where the authorities are accused of mounting a wide-reaching campaign of repression against ethnic minorities, including Uyghurs.
