Plenty of people did? That was obviously one of the end goals for cloud connected devices pushing recordings to a remote side for processing and storage. Especially when stuff like facial recognition was implemented server side.
I would be highly surprised if this was not pitched in the first internal product meeting.
While I give some grace to the regular population on this topic - anyone posting on HN should have trivially seen this outcome as not only likely, but nearly written in stone. Even if all your imagination captured was “secret NSA warrant” it would be one of the first risks you’d imagine for such a product.
It was obvious that this was the final outcome even back when Facebook first implemented tagging friends in photos before image recognition got cheap and good enough to go back and time and correlate the social graphs of everyone.
