The whole point of Internet of Things (aka CONNECT EVERYTHING TO THE INTERNET) was to make customers' life miserable in the medium-long run. Anyone who couldn't figure that out was massively deluded by the propaganda
that's one way to make people take a shit on the outside of the building...
also in Japan (where smart toilets are a thing) hackers were able to connect to toilets because nobody changed their pin code (it was on the default 0000)... and over in the asian world, they use water to clean their butt instead of toilet rolls.
Now these hackers made the toilets all of a sudden flush without any reason and piss everywhere in the bathroom...
