I feel like all of this IoT hardware should be rented rather than bought. If your piece of crap can suddenly stop working, I don't want to own it. Rent it to me and take it back when it's useless.
This is why the direction that the IoT market has decided to take things makes any of that stuff completely unacceptable to me. None of it can be trusted -- it is more likely than not spying on you, the way it works can change at any moment without notice, including ceasing to function.
Take a car for example. You can now lease the latest and greatest car, but you don't own that car, it's not your asset. If your in dire straits; where if you need to sell, you cannot, you don't own it, it's not yours to sell.
Not forgetting that the vendor then decides the price you pay. "Cool, due to climate change tax, we are increasing your payment". All you can do is pay the demand or live without a car which if you need to commute, your screwed.
What you might own may be junk, it still has a value. When you lease, you get none of all that. It's a worrying trend.
