Re: IoT vs Users
Nothing. It's a cartel. You take it back and find out EVERY machine/toaster/microwave does the same thing. Plus they won't have to rely on your WiFi going forward as they'll use Whispernets, so they can connect without your ability to control it (like you say, they'll brick first if they can't get through, so forget about caging them or breaking their radio stuff). And the government isn't your friend there, as they WANT this to happen for their Big Brother campaign.
Better consider going back to open flames and wooden iceboxes.
