The article is bitter sweet to me. Bitter because it's yet another little step in a huge march intended to erode freedom. Sweet, because they track WiFi signals.

In 2012 I started turning WiFi and location off on my phone as I left home. I remember the date because it's when London got 4G, and as of that date I no longer really needed WiFi, but I did need my battery to last the day.

It's become habit.

I always do it both to preserve battery and for privacy (and I never turned on location services) but a customer of mine, in the business of counting people entering and leaving stores, told me that about 60 to 80% of people has WiFi turned on all the time. That was a surprise. I would have taken a zero off those figures if I were to guess.
