Jake, I donāt think itās particularly scary.
We have been becoming more and more visible via electronic mechanisms over the years, and eventually we will have to learn to live with this. Tin foil hats probably wonāt help. So itās futile to knee jerk against this kind of usage of WiFi, because itās coming. Writing laws prohibiting things donāt actually prevent them happening.
Our society will change and adopt these surveillance systems as being the norm. Change is often uncomfortable for individuals, but it is pretty inexorable and we canāt do a King Canute and stop the tide.
