The problem is that cloud services are allowed for such things
I mean particularly with IPv6 all of those problems could be solved easily at home. If you want to look into the fridge while you are out, just press a button on it, it'll display its IPv6 address and a one time authentification token on its display (perhaps as a QR code). You snap it with your phone, decode the QR code and use your browser to access it. No cloud service necessary to spy on you. Since it's IPv6 you can have your public IPv6 address there and it'll just work.
However in any case, the main problem is that such solutions require a minimum amount of effort and competence. Current systems are catered to people who have no idea of what they are doing.
