Amazon makes money from those garbage companies having an ad war over who gets to deceive the eyeballs of Amazon's customers first, and then takes a cut when it gets sold.
Customer Obsession and Earns Trust might be two of Amazon's Leadership Principles, but no principles stand in the way of cold hard cash.
I agree with you about Amazon's leadership principals. It's clear that the retail side of Amazon regularly ignores them.
My favorite example of this was I was browsing the "top 50" computer science books on Amazon. This was about 10 years ago. In the top 50, they had basic how to books (like how to use Linux or Excel), books on getting coding jobs, etc. They had almost no actual computer science books and yet, the top 50 list software almost certainly created by people with a computer science degrees!! The list even listed the same title more than once in a few cases. It was obvious that the software which built the list was broken and either had not been tested or was deployed in a known broken state. Customer obsession does not mean shipping obviously broken software which does not help the customer.
As for trust, when I canceled Prime, Amazon used dark patterns to make the process as painful as possible. Not much to say other than I do not trust companies which try to trick me into not canceling a subscription I do not want.
Honest question: why would you trust any public company? Do they have any motive to do anything in your interest that isn't somehow calculated to benefit them monetarily in the maximum way possible?
