   @edward There's a whole scummy industry based around WiFi tracking:

   If you want to know why some shops offer free WiFi to their customers, this is the reason: it improves tracking accuracy.

   Always turn off both WiFi and Bluetooth when you're out and about. Turn them on only when you're in places you trust.

     When you're travelling on a train on the Elizabeth line take a look at the line diagrams posted around the inside of the train. In top right hand corner is a little message about "Wi-Fi data collection".

     If you want to opt-out then you need to remember to turn off WiFi on your phone every time you travel.
