The data is what makes them so good at keeping you on their platform, yes. But that data isn't inherently useful to the CCP. I think what GP is getting at, is that TikTok could easily start showing 80 million Americans whatever political agenda they deem appropriate.
1 week before an American election? 80 million Americans start being bombarded with "Why you should vote how the CCP wants you to vote" videos. That is a national security threat.
Edit: Changed "20% of Americans" to "80 million Americans"
