Amazon agreed to terms that allows Disney to behave in a manner upsetting to their customers.
Sure, Disney might not have signed on otherwise, but sometimes I wish Amazon, Netflix et al. would put up a tougher fight for pro-consumer rules on their platforms.
Amazon allowed Disney to remove access. You'll never see a company telling Amazon to recall physical goods it mailed out to people (without compensation no less).
Thats because Apple and other physical goods companies don't have a rider in their contracts with Amazon stating they can somehow force Amazon's customers to return their physical purchases. The contract they have with Disney allows Disney to do just that if they please.
