London subways to track passengers
jeudi 11 juillet 2019 à 02:00The London subways plan to track passengers' movements by their phone WiFi.
Supposedly this will be "anonymous", but I am sure they can put a name to most passengers.
I have taken pains to make sure my laptop's WiFi interface is always off except when I explicitly switch it on. Every time I reboot, every time I suspend and unsuspend, it switches off.
