There is a member of the Chinese government on ByteDance’s board of directors.

This is not accurate. ByteDance’s board of directors is comprised of five individuals, none of whom is a part of any government or state entity. 3 of the 5 are American. The board includes:
●Rubo Liang, ByteDance Chairman and CEO (Singapore-based)
●Arthur Dantchik, Susquehanna International Group (U.S.-based)
●Bill Ford, General Atlantic (U.S.-based)
●Philippe Laffont, Coatue Management (U.S.-based)
●Neil Shen, Sequoia (Hong Kong-based)
Four out of five of the board’s directors represent ByteDance’s investors on the board, and Rubo Liang, ByteDance CEO, represents the company and its employees.
