Via email from Chet (who worked with me at Microsoft on the location services for Windows Phone 7):
It is Big Tech that knows more about you than your spouse and that if they so choose could make your life miserable. As I discussed many times when we were working on location, carrying a device is like having a private detective assigned to you. Fitbit is just another source.
In East Germany they at least had to assign real people. Now, everyone can be tracked and monitored in real time without lifting a finger.
We have invented the tech that will enslave us.
This was in response to an announcement that Fitbit is now officially a part of Google.
He has a point.
But there is another point to be made as well. Intelligence sources, which your phone is, can be manipulated to your own advantage.
If your cell phone location is proof you were at some location then doesn’t your phone not being at some location prove (or at least represent evidence) you weren’t there?
