By “everybody” you mean everybody except Amazon. And I had fun hacking those. They were often on sale for like 2 bucks and they came with a battery that was good for like a thousand presses. You had to start the online setup process but not select any products, listen for the button’s msg to Amazon which contained a unique ID. You could then have your own server listen for a “pressed” signal from that button and do whatever you want. I keep meaning to find out if there’s still a way to initialize brand new ones.
