Yep - in fact any electronic device should have reverse polarity protection at a minimum.
But you opened a can of worms for me now 
talking about power supplies:
Gear with inadequate power supply smoothing/filtering, KIWF
Gear with humming/whining power supply, KIWF
Non standard external PSU, KIWF
Wall warts which are wider than the mains plug, or some other design flaw which means I have to solve a problem just to get them to fit in the socket, KIWF
Yeh unfortunately thereās a bit of nosing around now to get back to basics.
What I made sure of when I got my new MacBookPro late last year was to disable and opt out from the initial setup of as much cloud, siri, social media, etc as possible. I didnāt even set up my Mac ID initially. Also, never have used widgets. Clean slate thank you very much.
Ugh, Windows is like this too, I loathe modern operating systems trying to force this kind of shit on users. KIWF, then just to be sure NIFO.
Those fucking pointless LED lightbars that people put on their cars. (Usually oversized 4x4, that never actually go offroad)
Look closely, they light up the sides of the road very well. But they dont give any further Distance AT ALL.
All they do is blind people coming the other way. Fucking thanks, now Iām blind, and cant see for the next fifteen minutes because my retinas are burned from your stupid LED light bar that you dont fucking need because mormal headlights are enough and youve got your foglights on. Cretins.
KIWF NIFO
I think theyāre illegal in many countries. You canāt invent your own lights.
My gf and I were staying in an airbnb recently and when she made a salad one night she used the olive oil there without really looking at it. Well, it turned out to be ālemon olive oilā, which is a really putrid invention. I have no idea who could like such a thingā¦ tasted like how I imagine Mr. Clean would.
Those fucking one-page Roland manuals that are almost impossible to navigate on a phone 
I like it 
But my gf also hates it. She says that it smells like dish washing soap.
I have never witnessed a right use for the raspberry vinegar neither. What an awful meal destructor!
The Korg ones tooā¦
And the printed ones the size of a tablecloth, that are folded a million times, with 88 languages with each āpageā printed in each language in turn, so that you have to scan the whole thing for the next page in your language, but you need to use a microscope to read it because the text is smaller than microfiche text. Oh and the green background for the text, mustnāt forget that. Absolute bellends.
KIWF, NIFO.
Edit: oh and printed on the thinnest, nastiest paper so that they are almost opaque, bonus if you get a paper cut before you rage quit and scrumple it into a ball before headering or drop kicking it into the nearest fire.
Corriander.
NUKE IT FROM ORBIT
Those little plastics tags that hold labels onto things like new clothes.
Edit: these things
I had one for a reversing lightā¦ and as a curtesy reminder for tailgaters with their high beams on 
NIFO, and the factory that makes them.
Do you all feel better yet 
No, but I will once everything on this list has been rendered to smouldering ashes
I like it in my ice cream
We sprinkled it on our blancmange back in the 70ās, that or fag ash, depending on budget, same taste, half the fat.
When I say blancmange it might have been artex.
