Why would I ever connect my fridge to the internet? I cannot fathom any feature on a fridge that would incline me towards giving it the wifi credentials.
That's probably because you're a developer, and as developers it's really easy for us to develop tunnel-vision for some reason, and really hard to see the perspective from a "regular person", the sort of person who a salesperson can say "You can now get alerted when you're low on eggs, no matter where you are!" and the person will think that's a cool feature with no drawbacks.
