The biggest example to me that Amazon no longer cares about the customer is their experience for non-Prime users. Random, regular items like Blu-ray discs or diapers will randomly get marked as "Prime Exclusive", and cannot be ordered from Amazon without a Prime subscription, even at a higher price. Prime Exclusive items are, mystifyingly, not even a better price, and usually the same or cheaper elsewhere. Amazon is literally giving you the choice to get Prime or shop elsewhere, and... I go shop elsewhere. Completely mystifying decision on Amazon's part.
Amazon just seems to enjoy screwing with anyone who doesn't have Prime, and has done it for years. It's never gotten a lot of coverage because of the pervasiveness of Prime: Anyone reading this comment probably never knew this, because they already had Prime.
