Similar stuff has been around for decades. There was(maybe is?) a “search engine” called shodan which allowed you to search for devices open to certain protocols, one of which was used for security cameras and even an option to only show systems which didn’t request a login. You could go on there and see literally thousands of people’s homes and rooms. This was pre-2010 so atleast a decade and a half ago and no one cared.

Now atleast most camera systems require a login by default but other than that…
