Internet Connected What??

I gave our son my old coffee machine a while ago but it started to make strange noises whilst doing its coffee thing so we went to the coffee machine shop to inquire about buying a new one and they all looked a bit flimsier and had a lot more buttons and some included WiFi and Bluetooth.
I asked the nice shop salesman why it would need WiFi and Bluetooth and he said it was so it could be updated over the internet which seemed a bit mad so we went for one which didn't come with an app but i later heard of something which was even madder, so much i thought it was a spoof at first, an internet connected smart mattress.
There was a Cybersecurity expert and he was talking about security concerns about the firmware in the mattress which allowed backdoor access and full arbitrary code execution capabilities making the mattress a disastrously unsafe device to keep on a home network...or something like that because i was stuck on...there's an internet connected mattress??? WTF???
Nope it was not a wind up, there really are people who pay £2,000 for the mattress and a subscription of £17 per month for  'bed control and bed monitoring and sleep-enhancing features' which include heat control, automatic firmness adjustments and other settings to optimize your sleep surface through the use of sleep tracking sensors.
Brilliantly, during the major Amazon Web Services (AWS) outage last week the people who actually shelled out for a internet connected mattress found that the lack of internet caused chaos in bedrooms across the UK because the mattress designers didn't think to include an off switch and were stuck at high temperatures and odd positions in the night because something they do if you don't pay the subscription fee, (or disconnect it from the internet) is turn to such an angle to be unusable.
So many questions but mostly, what genius pays £2000 for a mattress that monitors everything that you do in it and then holds you hostage and turns completely useless if you don't pay the subscription fee, or the internet blinks off?
