"Users in Google's home state of California started complaining that their lack of foresight came to bite them on their ass..."
I must admit I thought this sort of IoT stuff might have been a driver for IPv6 adoption so peoples apps could talk directly to their home LANs since few homes have fixed IPv4 address. But noooooo, the "stop-gap" of using a central server for the remote app and the home LAN to communicate via has become the norm thanks to greedy companies wanting every last bit or data they can slurp under the guise of users can't be expected to pay more for fixed IPv4 addresses and can't be trusted/bothered to set up some form of DynDNS type service.
