Ex-ByteDance worker claims TikTok owner stole content, inflated user numbers in lawsuit over firing
- Roger Yu Yintao claims ByteDance fired him for reporting concerns about a ‘worldwide scheme’ to steal content and fabricate user engagement metrics
- Yu, a California resident, joined ByteDance as head of engineering in the US in 2017 and was terminated the following year

Roger Yu Yintao said he learned soon after he joined the company in 2017 that ByteDance had for years undertaken a “worldwide scheme (including in California) to steal and profit from the copyrighted works of others”, according to his complaint filed Friday in San Francisco state court.
He also discovered that the company was programming fabricated users to “like” and “follow” real user accounts to boost the engagement metrics relied on by potential investors, according to the complaint.
Yu alleges the company was driven by a “culture of lawlessness” that focused on growth at all costs.
“He was surprised by the brazenly unlawful conduct within the company, which was euphemistically excused as ‘entrepreneurship’,” according to the complaint.
TikTok has been under intense scrutiny from Congress and a federal national security review over concerns about potential influence from the Chinese government because ByteDance is based in China. Multiple bills have been introduced that would limit or ban the app in the US.
