Can someone summarize what would make the sort of data TikTok generates useful to the CCP? I could assume there are a few needles in the haystack-- capturing location data from some new recruit who is filming in a secure location, or some 16-year-old gets mom's patent application in frame while twerking. But it's a huge and very expensive haystack to create and search. I'd think most nonclassified-level insights they could get are also easily obtained from commercial data brokers. It would be interesting to try to leverage "cool" for military/political advantage. I can't really imagine it working in anything but a terribly cringy way. On a broader level, I feel like there must be people in PLA research labs saying "Okay, so American teenagers are even more embarrassing, shallow and petty than our prior data indicates."
