I don't doubt that Bytedance shares Chinese TouTiao user data with the Chinese government, akin to how Apple does it with iCloud, but Bytedance has been pretty adamant that TikTok is external to China and doesn't share data. Even when there was an executive order to ban TikTok for being a national security threat, they couldn't prove that it was.
Does anyone have actual evidence of TikTok sharing with the Chinese government, outside of political hit pieces like the one above?
