but cannot phones simply be tracked by their own id regardless of carrier. Say you swap from Verizon, if you hit one of their towers they could theoretically use that information even if your not a direct customer.
We know the FBI is reading the traffic so I am wondering why someone is surprised a company does it. Its not right for either party
they could also follow you non stop on the street and enter every store you go and take note of all your purchases by looking over your shoulder. and i don't think much of it is illegal unless you can prove it distress you
but I'm not a layer (I'm a productive member of society :)
