Yintao Yu, head of engineering for ByteDance's U.S. operations from August 2017 to November 2018, filed a wrongful-dismissal suit against the company in May 2023. In the filing, Yu claimed that ByteDance's Beijing offices had a special unit of Chinese Communist Party members, sometimes referred to as the Committee, which monitored the company's apps and "guided how the company advanced core communist values." ByteDance is the Chinese company that owns TikTok.
