So in the future it won't even be possible to visit a friend's front door without being tracked by Google/Amazon/Facebook/etc? A while back a friend of mine bought one of these "cloud"-connected doorbells, and hadn't even considered the privacy implications. After I explained it to him, he thankfully returned it and went back to using a normal doorbell. People who install these should be forced to install a sign just outside of the camera's view informing visitors that, by proceeding to the door, they agree to Amazon/Google/whoever's privacy policy and ToS.
