If you buy a dishwasher with a camera or network connection (and actually plug it in) and have no clue how to properly setup your home network - sure, but it's kinda ridiculous.
Also, fun fact, some Russians think that USA put some sort of backdoor in all their tech so they can remotely destroy it. Years of reverse engineering proves this to be false, but hey, you often can't change peoples mind. But it doesn't change the fact that any piece of internet of things can be hacked into, so you can easily get access to a network by hacking into not protected coffee machine.
