Broadening a thought: We'd be better off if we stopped talking about "the internet of things" and started talking about "computers don't always look like we expect them to".
Instead of saying "internet-enabled" it might be wise to say "regardless of what it looks like, that's a computer and you should treat it like one".
"Somebody hacked my fridge!" Yes, your fridge has a computer built into it and you should treat it like a computer (and demand that the manufacturer treat it like one).
