I was curious about this as well. Hypothetically, if they are really trying to extract insight, they could be:
- Industrial trend pattern: even if only people accidentally leave the Cloud Feature on initially, there could be some that slip through. It could be product categories way before the public knows about it.
- Defence and aerospace: obviously less likely, but if people use Strava in odd locations, and people share classified defence info on War Thunder, then it wouldn’t surprise me if someone slipped something through.
It wouldn’t surprise me if such automated analysis is setup somewhere in China.
