When is it time to say 'No' designing a pain giving device?

I just came across the Pavlok a device that by design is to cause pain; Reference: Pavlov's Dogs.

THE FIRST DEVICE THAT BREAKS HABITS BY DELETING TEMPTATION.
PAVLOK ASSOCIATES A MILD ZAP WITH YOUR BAD HABIT, TRAINING YOUR BRAIN TO STOP LIKING THE HABIT.
THE ZAP IS AN ELECTRIC SENSATION THAT RANGES FROM PLEASANT TO SLIGHTLY UNCOMFORTABLE.

I realize the debate about designing weapons that kill people have been going on forever and we are not likely to have answers to that debate here.

What happens when the software in the device or its control app have bugs? What are the security of the device being 'hacked' or used by the mysterious evil 'Them' (fill in your choice of conspiracy group)?

The one that really puts it over the top for me is linking this pain giving device to Smart Meters. Set your thermostat to high you get Zapped. Is this really the world we want to be creating with the Internet of Things (IoT)?

'Road to hell'

...Prof Alan Woodward, a cybersecurity expert from Surrey University, said the more connections which are made between devices, the greater the risk of a security weakness.

"Having a convoluted interaction between systems is almost inevitably going to lead to unintended security flaws," he said.

"I know this type of technology is developed with the best of intentions but the road to hell is paved with them."

Having watched my late wife suffer from Chronic Pain for years I will refuse to be involved with any device that causes someone to experience any level of pain. Karen's Journal is required reading at Duke School of Medicine.

Karen's first-hand account of her illness gave an honest, heart-wrenching depiction of what it is like to live with debilitating pain day-to-day. -- The Derrick Newspaper, Sept 8th 2014.

Internet of Things (IoT) possibly Carcinogenic to Humans

An obscure part of the World Health Organization, the International Agency for Research of Cancer (IARC), published an even more obscure paper: IARC Classifies Radiofrequency [RF] Electromagnetic Fields as Possibly Carcinogenic to humans in 2011.

I bring this up as Epidemiology just published (January 2014 - Volume 25 - Issue 1 - p 23-27;doi: 10.1097/EDE.0000000000000028) Commentary: Mobile Phones and Cancer: Next Steps After the 2011 IARC Review. I've covered this area before so I'll refer you there rather than repeat it here. See also Something Is Rotten in Denmark: Danish Cancer Society Plays Games with Brain Cancer Rates and IARC Monographs on the Evaluation of Carcinogenic Risks to Humans.

Something else bothers me about the push for the (unneeded?) Internet of Things (IoT). Lots of places talk of or show how to power the low power sensors and such from 'ambient' RF power taken from the environment, such as a local TV or Radio Station. At what point does the source transmitter get overloaded with the million(s) of IoT devices drawing power from it? What do the owners of these transmitters think of this? Isn't this technically illegal under the same laws that prevent farmers from drawing power from the power company via inductive coupling to their mile(s) long electric fence wires?

Ponder this, as related to many receivers drawing from a single transmitter: If I strike a tuning fork in a room of a 1000 identical tuning forks what happens? Leave your answer in the comments.
