Your washing machine could be sending 3.7 GB of data a day — LG washing machine owner disconnected his device from Wi-Fi after noticing excessive outgoing daily data traffic
It only would be a big problem if household devices like washing machines are built in a way that makes a connection to the internet mandatory in order to function properly. Imagine you can't do your laundry because of an internet outage.
Name any household device (washing machine, dishwasher, dryer, toaster, water kettle, iron, coffee maker, (microwave) oven, ...) that has been improved in functionality by connecting it to the internet, making it a internet-of-things-device. I can't think of any.

I once heard of a toaster that could download patterns (character faces and so forth) then burn them onto your toast. Totally novelty but kinda cool if you could have Batman toast with breakfast. I don't know if it actually exists as a product or was just a proof of concept though.
