I wonder how many more decades of screaming into the void will be required for it to be taken seriously by those who deny any/all security efforts until after the disaster has already happened (and then still will only approve the absolute minimum required efforts)...

Formal methods for reliable software and properly configured systems secure by default.

Of course the bigger question is why a refrigerator is even a "connected device".
