China has faced very few consequences for its continued detainment and torture of Uighur Muslims, in large part because its concentration camps provide something many corporations aren’t willing to pass up: profit.

Add Apple to the list of companies benefiting from China’s horrific human abuses. The Washington Post reported this week that Apple’s oldest and most well-known supplier has been accused of using forced Muslim labor in its factories. The Tech Transparency Project, a human rights group, alleged that thousands of Uighur workers detained in China’s Xinjiang region were sent to work for Lens Technology, which supplies not only Apple, but Amazon and Tesla as well.
