Oh dear god, why did you connect your iMac’s Ethernet port to mains? Did you expect it to survive?! The fact that Ethernet functions the same with a voltage bias across the leads is exploited for PoE — power over Ethernet.

Going to throw out a guess and say it's because selling you an item after you called it a bong is admitting that it's indeed a bong.
Ah, that makes sense, question answered. My second question is that if bongs and water pipes are the same thing, why does the law distinguish their purpose by their name? It seems like given " I want to buy a water pipe for smoking the marijuana " and " I want a bong to smoke tobacco ", the second should be legal to request, not both.
if you intend to use that power tool or crowbar to break into a house it’s “possession of burgular tools” and a felony, if you’re a contractor there to install some drywall it’s not.

Actively using it to harm others is different than just creating it.
Creating it and selling it is an obvious attempt to profit from the custom of those who wish to use it to actively harm others. There's literally no other reason for anybody to buy an "anonymous" one over a standard one which says what it does on the stick, and yet they're charging $5 more for the anonymous one...

I vaguely recall the argument (maybe buried in the USBKill site) that manufacturers could ~easily limit maximum voltage across the data lines. Maybe using a resettable fuse? I know that Raspberry Pi limit USB input voltage to ~5V, for example.
Raspberry Pi limits the input voltage with a Zener diode across the input. In a Zener used this way, the current flow through the diode varies with the voltage difference between the input and the output - so with enough voltage input you can still make it fail, as you can exceed the max power dissipation of the diode and then it will burn - and after that, your circuit is not protected anymore.

The innocuous use of TV-B-Gone devices was to shut off at once all TV sets at malls; it was rather a prank than a destructive act, with the added benefit of getting some peace.
Was there a TV-come-on to turn on the mall TVs in the morning?
I am looking at https://usbkill.com/ . What is the purpose of the device? The manufacturer calls it an "ESD tester" yet there is an "anonymous" version available: https://usbkill.com/products/usb-killer-v3?variant=447760856...
Maybe could be handy to distroy terminator robots and inactivate war weapons in the future. Who knows?

Actually there is theft, for example, I watched a TV program about shoplifting and they caught several people, like a company of school girls or an old woman. The bicyles must be registered in Tokyo if I remember correctly. Also, they have unmanned selling stalls, usually in the countryside, where farmers sell fruits and vegetables [1] [1] http://abritishprofinjapan.blogspot.com/2017/07/unmanned-veg...
There's an interesting reason for old people getting caught shoplifting in Japan. One of the many articles covering that: https://www.bbc.com/news/world-asia-47197417

> Is the device safe? > The USB Kill and the USB Kill Testing Shield are safe to use. Both devices have been manufactured, tested and certified as CE Approved. Test in complete confidence. This device that is designed to destroy computers is perfectly safe to use ... I don't know what to say to that.

Speaking of power banks, what would happen if you plugged this device directly to one?
most power banks don't have the data lines, and as far as I see this device uses the data lines to destroy the host. So I'll guess nothing would happen.
That's much harder though because power lines tend to have big-ish capacitors on them.
