"they could actually carry out real world testing in the field"
And there we have it : the true nature of IoT.
It is not to make your life easier, it is to allow corporations to freely spy on your habits, gather data on you and sell that to some advertising agency to make more money off your back.
Oh, of course, it will be said that they are doing that "to propose products better suited for the customer". Sorry, I don't buy it. The current products are sufficiently suited for customers ; we like having the choice.
My laundry machine has 7 programs. I always use the same one. The others don't bother me, they're there if I need them - which happens once or twice a year. Do they want me to believe that they will make a laundry machine with only 2 settings ? Nonsense.
I'm sure of one thing : this article is just reinforcing the IoT ban field that is around my house. Not only do I find IoT rather gimmicky if not outright useless, but now I know to look out for yet more spying features.
I really need to dig that bear pit around my house someday.
