Nothing shows this like the switch from showing recommended books/products to showing ads.

Ads generate more revenue today, but I can't find good books to buy an Amazon, so I go elsewhere.

It's clear which is better for the customer (and for Amazon long term), but they can't give up on the revenue stream, even if it will eventually kill them (since it drives their customers to other platforms, and provides a place for competitors to grow).
