Why focus on the NSA or the intelligence services.

The fact is that many private companies have this vast amount of data, the big push with mobile device advertising was the accuracy of the geo-location. The fact you can offer really well targeted adverts.

These companies build profiles on everyone, but unlike the intelligence services who have a mandate which as some level is for our own personal good, these companies have no such thing.

The concern is that we are embracing devices that provide little, no, or obfuscated control over personal privacy.
