They're owned by the CCP (and before you say they're not, the ByteDance C-suite is basically all current Chinese citizens and the headquarters is in Beijing).
Businesses and people do not have rights in the way most westerners are used to. Assume anything out of China or generally owned by Chinese companies is a direct arm of the CCP ... because even if it isn't today, the CCP can unilaterally throw down an order from the top and take control of the company/have them do whatever they want or the leaders replaced.
