>> But it is not stolen property. So you cannot compare it to these laws.
It was stolen by the seller on Amazon. You acted perfectly legally but did receive clear title to the copy.
Amazon was notified of the theft by the rightful owner of the copyright and thus had to take the stolen property back and recompense you.
You should be aware that only some of the books on Amazon are sold directly by Amazon. A large number are also sold by third-party sellers, who, among other things, swear that they have the right to sell the work.
In this case, the seller, not Amazon, was the thief. Amazon merely sold you something guaranteed by the seller and took a commission on that sale.
