Anything can be slippery-sloped into being horrifying for privacy. If there were some kind of sensor that could detect, say, physical child abuse and nothing else—no video, no audio, just a binary yes/no is there physical child abuse (assuming an appropriate statutory definition of physical child abuse) you bet there would be lots of demand for that sensor -- and you could have reasonable conversations about false positives, risks of other data getting out, etc. The difference between Telegram private chats and "unmonitored housing" is that the former has that kind of sensor available, and the latter doesn't.
