I've got a couple Network-of-Things lightbulbs, specifically miLights, that allow me to change the brightness and color temperature. They use a sort of hub to connect to the network, which in turn lets Tasker control them. Do I need them? Certainly not. Do they make mornings far more pleasant by slowly ramping the light up in brightness and color temperature? Yes, they do. Are they connected to the internet? Absolutely not. When I set them up, I specifically set my router to not allow any traffic from the hub or to the hub to cross it at any time. Does the bulb work just fine in this configuration? You bet. It doesn't need to connect to the internet to work, so I don't let it. Same thing with my Edimax smart plugs. In the future, however, these kinds of things may not work without an internet connection, despite really only being useful locally. When you go out and buy a new Mr. Coffee, even if you don't want or ever use the smart feature, the only way to get it to brew would be to connect it to the internet. Then when you go to sue them because the security on it is atrocious and your network gets hacked, you're stuck because there's an arbitration clause. This is what they're concerned about, not something superficial like 'my lightbulb won't go anymore'.
