The US use of it isn't the concern, we can regulate it and I do not see a reason for many agencies to have the tool or its like. What people should understand is once this tool exists then oppressive governments can either get hold of it and create their own. So go pick your favorite country known for oppressing people and you can guarantee this or similar is in use. So what this leads to is further work on not allowing information of any sort off a phone unless approved by the user and features that let them know which apps have sent data and how much. Kind of like how tracking is being defeated on the desktop. Pretty much the end run is burner phones/prepaid but any organized individual or group of who does not want to be tracked would or should already have gone down that route. Of course that only works to a point, where a large number of them congregate can provide agencies a lot of information as well.
