I honestly do not know where to begin with this article. I believe the most logical place to start is I have no doubt similar problems may exist within devices from other mobile operating systems. I doubt this is exclusively an Android or Google problem. That said, it is deeply concerning, especially given the data collection and sharing process going on in the absence of even an active SIM card.
I am not advocating for the mass production of tin foil hats, but I will say this. If you have your smartphone with you, you are most certainly never alone.
