At least the US government can’t harvest US citizens social media data without a warrant (excepting all the patriot act stuff). But there is zero protection for your data from the CCP if it’s on TikTok. That’s understandably a pretty huge security concern. I can also understand China not wanting data from their citizens in the hands of American social media companies. Idk if any if it is good or bad but it’s certainly common sense on a national level.
