Google has much better security than the phone companies anyway, so letting the phone companies know where you are is bad enough.
I had the idea to "red team" myself and find out if there's a way of finding out my location history from shady online data broker and then take countermeasures.

By design, Android will search all Wifi SSID's and send the GPS coordinates back to Google, so that if another phone not using location services connects to that router, Google knows their location by cross-referencing with the stored GPS coordinates.

You can turn on airplane mode in the OS, but it could still choose to reactivate the radio for short bursts without you knowing. Or the the radio could be set to phone home on a regular basis on its own recognizance. This could potentially occur even if the phone is turned off. There is no way to ever completely trust a cellular device.
