I think there's probably no way we can trust the data isn't going to China. This is China we're talking about.

But I don't even think the real problem is videos of high school girls doing choreographed dances going to China. The problem is psyops and disinformation. I think it's much more likely TikTok could be, and probably has been, used to sow political discord. It's not hard to imagine the Chinese government "suggesting" to TikTok that they alter their algorithm to promote content that, say, discourages people from voting, or promoting political violence, or eschewing vaccinations.
