Allow me to ask some questions :)

No reason to think this is only US right?

How & when is this transmitted and what other data apart from lat & long?
> pretty much anyone on the installed OS [...] is getting a copy of your location data
You mean the devs of whatever app is installed on the phone? The outgoing data should be visible in things like Charles proxy, right?
Is this analogous to FB data being available to any dev that gets permission to access your profile?
> It's normal to track hundreds of millions of people a day and trade stocks based on where they go
Whaaa ... ? Do explain, fascinating.
Can this all be mitigated by those smartphones-hardened-for-criminals type devices?

The stock trading I've heard of, and even seen news articles about before.
Location tracking lets stock traders know how well a store is doing well before public results are announced. If foot traffic is down at a store, time to sell off (or short) the stock before it becomes publicly known.
