Well, if Amazon has suffered a hack, rest assured they will compensate their users 100%, even to their own loss. I’ve dealt with Amazon a LOT, as I’m a frequent shopper. They have the best, most forgiving, most customer focused customer service I’ve ever seen. I even send them emails telling them so lol.
Amazon most certainly has a clause protecting them from claims of lost data.
Amazon admits it was a bad update and not a hack.
