But Alexa would have to be a lot more intelligent and plugged into a lot more systems before it could do tasks of any complexity--especially tasks with financial consequences.
There's maybe half a dozen things I use Alexa for and none of them involve giving Amazon a nickel.
I think the deeper issue is that when Amazon started the product (I heard rumours of it circa 2014 or so?) Amazon was a trusted retailed. Stuff was cheap and generally good. Now it's a scummy marketplace filled with fakes and frauds. I'm not buying anything off it until I've deeply reviewed what I'm about to buy.
<...> and even then you might get a fake from due to commingled inventory. Even for books ([1], [2], [3]).

When you pressed the button, you know what you were buying and how much it cost, because you're the one who set it up.
As for how to determine whether the purchase went through or not, an LED would light/flash on the button to indicate success/failure, and you'd receive an email with more detailed information such as the item being purchased, its cost, and the address where it will be shipped. If the button press was a mistake, you could simply cancel the order.
When they discontinued the service, I put all the buttons in a cabinet drawer hoping that they could be "jailbroken" to act as an arbitrary IoT button in the future (like the official Amazon IoT button[1]), but as far as I can tell this never came to fruition (barring a few exceptions) and they're basically doomed to e-waste.
And not a bad idea, just one that didn't play out.
I certainly wouldn't call it 'so wrong'.
It's been a pretty huge money sink because most people turn out to be more like you. If I were your friends I'd be polishing that resume just in case.
