Right, but that apparently isn't happening to enough people, so these different means to erode our reasonable expectation of privacy will continue to grow. As they do governments can hold up Ring cameras for example and say, "look, everybody has one of these on their front porch and they're filming their neighbors. If you let a private company do that then there's nothing legally keeping us from doing the same."
It's pretty blatant in my neighborhood already. Whenever something criminal happens and cops come around one of the first things they ask is if I have a Ring doorbell they could take a peek at.
Those who are burnt by this trust, tend to change their mind quickly.
