(this was meant to be snarky. i'm just a developer with a calendar app that requests location data to humbly provide location place recommendations... no monetization, no sharing of this data, and it's essential to being able to fill out the "location" field accurately. this constant stream of negative attacks against apps not built by FAANG is destroying trust in independent apps, due to the actions of a few bad actors. ironically, this is just driving people back to a handful of monopolies who monetize user data in-house. the winner here is google (and, let's be honest, they are probably already doing something with the location data we're sending them to get the nearest place ids).)
Respectfully, one goal of doing this research was to shine a light on those who are engaging in these practices, so that users who dislike it can potentially find alternatives.
This is a good thing for any apps who do things right.
