> What's China going to do? It's a far away country I don't live in and don't care about.
Extortion is one thing. That's how spy agencies have operated for millennia to gather HUMINT. The Russians, the ultimate masters, even have a word for it: kompromat. You may not care about China, Russia, Israel, the UK or the US (the top nations when it comes to espionage) - but if you work at a place they're interested, they care about you.
The other thing is, China has been known to operate overseas against targets (usually their own citizens and public dissidents), and so have the CIA and Mossad. Just search for "Chinese secret police station" [1], these have cropped up worldwide.
And, even if you personally are of no interest to any foreign or national security service, sentiment analysis is a thing. Listen in on what people talk about, run it through a STT engine and a ML model to condense it down, and you get a pretty broad picture of what's going on in a nation (aka, what are potential wedge points in a society that can be used to fuel discontent). Or proximity gathering stuff... basically the same thing the ad industry [2] or Strava does [3], that can then be used in warfare.
And no, I'm not paranoid. This, sadly, is the world we live in - there is no privacy any more, nowhere, and there are lots of financial and "national security" interest in keeping it that way.
