I could see News like in this
"An elder starved to death after his refrigerator got hammered by a DoS (Denial of Service) by hackers and was unable to open the fridge."
"Hackers are wrecking havoc with consumers as they find their refrigerator keeps turning off and are forced to re-buy all their frozen food. Local supermarkets are staying mum for fear of retaliation."
And there is the potential of all the EF spectrum "pollution" as all these stupid IoT devices are constantly broadcasting:
"Scientists have completed a 30 year study and have found WiFi devices raise the risks of disease statistically significant."
I'm not saying there *is* a problem, just that there -might- be one after we've had long term uses and studies involved.
