If Chinese are to built an instrument of war they would need a lot more data than who my friends are, my favourite places to visit, or the songs I listen. They can't make use of anyone's personal data unless they happen to be working with Indian government in department of security.
What if someone who do work with department of security buys a Xiaomi phones. Sh!t!
There's a highly researched topic called behavioral analytics. You'd be very surprised to know how a trend is analysed with all this data. Ultimately, the aim of such organizations is crowd control and manipulation.
Your friends list, the websites you visit, the images you take might all seem unimportant and pretty much useless to you; but, that's in your own context.
What would
I do if I have access to the said data for a thousand people?
Map an event that is visible to the said sample space of 1000 people, say the Russia - Ukraine issue. Take notes of the frequency of mentions of the countries, record opinions etc.
People open up and lash in private, thus we derive pure opinions from tracking their messages. We'd also get to know how much a person ignores the said topic (why is this relevant? because the targeted sample is assumed to posses the basic skill of reading news, and thus another metric of how a population is aware of current affairs is generated)
Geolocation, well duh - travel patterns, spending patterns, browsing patterns and even the number of clicks you make is relevant now, in this world. This is just a wild guess of options I typed up in a couple of minutes. Imagine a scientist doing the same.
Now with all this pattern data and information, the final question comes "What's the bloody use?"
Well, information is power. When you're the ambassador to India, I'll just send you that selfie you took with your sister's makeup then suddenly deleting it without realizing it actually went though the cloud storage and thus our servers. ggwp
