How is that hurting you? How is your every movement being tracked by a single agency such an issue? They said they would keep it private, pinky promise.
An extreme case is on the other side, is to compare simple site limited tracking to a coffee shop being able to see who enters the door. Why should they track how I look and the way I'm dressed? Does it make service harder if you have to work blindfolded? Though luck, my privacy is more important than your wish to provide your customers with good service.
In your example they are only looking. It would be different if they were recording their observations in a structured manner (aka cameras). Even writing it down by hand would raise flags, would it not? Sure, being a human means looking at me and my coffee to brew it, but recording everything I do in (semi)permanent storage? Is that human? Is that necessary to brew coffee?
