I am on Louis Rossman's wavelength when it comes to this:
Amazon *shouldn't* be doing this sort of thing.
There's also no technical reason why amazon or any other company cannot create a device that functions independently and cannot be remotely rendered useless like this. It is a choice that they all made.
Outside a technical community, people know virtually nothing about this technology. The only long lasting solution is for people to be informed about this topic, and if they value privacy, independence and the right to actually own and control what you've purchased, only they can make the choice to continue using these products or not.
Trying to find other measures like legal means can certainly have a place, but it's always a cat and mouse game of companies trying to circumvent them. They have pretty much all made it clear that they WANT to have this level of control and access to your daily life.
It use to be that Amazon, was a very 'customer' orientated business (maybe they still are, but I'm not 100% sure). Bending over backwards, in all sorts of ways, to keep their customers happy. Even if/when it meant making a loss on some sales.
Such as great no hassle, very easy returns, honest items (when Amazon was the actual seller), and use to be (a somewhat long time ago), that Amazon was the only seller on Amazon (if I remember, correctly).
They also were generally the cheapest supplier, for most items they sold, in the past.
These days, I suspect Amazon is beginning to slip on the customer service front. I don't think they are still the cheapest supplier (especially for very low cost items), any more, either.
I get the impression a change of management at the top, is gradually shifting Amazons business practices. Away from being this super nice guy (friend), at least for the customers (much, much less so for the suppliers). To being just another business, that is just out to make money, any way it can, even if it hurts the customers.
I also think, Amazon is becoming too much of a monopoly (or whatever the right expression is, to describe a business that has become too big for its boots).
E.g. An honest business, that sells a huge percentage of its items, via Amazon. Could suddenly be dropped, because of one of a number of reasons, that has broken one or more of Amazons 'rules'. Which could end up badly damaging that business, and possibly mean some people at that business lose their jobs.
If Amazon gets too big (or already is), they could end up harming customers, through excessively high prices and little or no viable alternatives, because of their monopoly like situation.
If a customer, just lost one service to their home and just one item stopped working, because of a minor dispute. E.g. An online cloud service that lets you view some pictures you uploaded to it. That would not be that bad.
But if you get into some kind of dispute with Amazon, and a huge number of services (such as losing access to your only mobile phone number, and hence lose your own customers, as you can no longer take any more small business calls). Then that would be a disaster for the individual(s) involved.
