Across #China, tens of thousands of people tagged as troublemakers…are trapped in a #digital cage, barred from leaving their province & sometimes even their homes by the world’s largest digital #surveillance apparatus.

Over the past quarter century, American #tech companies to a large degree designed & built #China’s #surveillance state, playing a far greater role in enabling #HumanRights abuses than previously known, an AP investigation found. They sold billions of dollars of technology to the Chinese #police, #government & surveillance companies, despite repeated warnings from the #US #Congress & in the media that such tools were being used to quash #dissent, persecute #religious sects & target #minorities.
