When contacted by the BBC, a ByteDance spokesperson strongly denied the allegations: “We plan to vigorously oppose what we believe are baseless claims and allegations in this complaint.”
They also said that Mr Yu was employed by the company for less than a year and in that time worked worked on a now-discontinued app called Flipagram.
“It’s curious that Mr Yu has never raised these allegations in the five years since his employment for Flipagram was terminated in July 2018. His actions are clearly intended to garner media attention,” the ByteDance spokesperson added.
