My question would be: is the value provided worth the cost to the taxpayer?

Part of it is profiling, data gathering, and part of it if you happen to mention something that is not-supposed-to-be-mentioned, you will be targeted by private comms, job offers, etc. to collect further info.

Edit: for example, US military is buying locations data from a Muslim prayer app (1). You can assume also same happens for other apps by other 3 letters agencies, like dating apps, social media (including HN), and others. No action needs to be taken, just data gathering for whenever it’s needed.
