How is it fair, when the vast majority bought the deal because of the stamina, and the fix includes absolutely no stamina for the people who purchased it?

If you ordered AirPods from Amazon, at the wrong price, and Amazon said “sorry we had the wrong price for AirPods listed, so instead we are sending you a calculator, a cute stuffed animal, this shirt, and a case for the AirPods we are not sending you” that would not be acceptable. At all. In fact it would lead to some pretty bad problems for Amazon.
