A former executive fired from TikTok's parent company ByteDance made a raft of accusations against the tech giant Friday, including that it stole content from competitors like Instagram and Snapchat, and served as a "propaganda tool" for the Chinese government by suppressing or promoting content favorable to the country's interests.
The allegations were made in a complaint Friday by Yintao Yu, the head of engineering for ByteDance's U.S. operations from August 2017 to November 2018, as part of a wrongful termination lawsuit filed earlier this month in San Francisco Superior Court. Yu claims he was fired for disclosing "wrongful conduct" he saw at the company.
In the complaint, Yu alleges the Chinese government monitored ByteDance's work from within its Beijing headquarters and provided guidance on advancing "core communist values."
Yu said government officials had the ability to turn off the Chinese version of ByteDance's apps, and maintained access to all company data, including information stored in the United States.
ByteDance did not immediately respond to a request for comment.
The allegations come as TikTok – one of the most popular social media apps in the U.S. — faces heightened scrutiny in Washington and some states about whether it can keep American data safe from the Chinese government. The Biden administration has threatened to ban the app if its Chinese owners don't sell their stakes.
TikTok maintains it never gave U.S. user data to China's government and wouldn't do so if it was asked. In an effort to avoid a ban, it also wants to store U.S. user data on servers operated by the software giant Oracle.
In another attention-grabbing part of the lawsuit, Yu alleges he observed ByteDance promoting content that expressed hatred for Japan on Douyin, the Chinese version of TikTok. At another time, he said the company demoted content that showed support for the protests in Hong Kong while promoting content that expressed criticism of the protests.
Yu said ByteDance developed software that would scrape user content from competitors' websites without permission. He alleges the company would then repost the content on its own websites — including TikTok — to attract more engagement from users.
Yu said a fellow TikTok executive in charge of the video-sharing app's algorithm waved off his concerns. At some point, Yu said the company modified the program, but continued to scrape data from U.S. users when they were abroad.
The former executive also alleges the company created fake users to boost its engagement metrics, including by programming them to "like" and "follow" real accounts.
Yu is seeking punitive damages, lost earnings and 220,000 ByteDance shares that had not vested by the time he was fired.
