I'm dubious. Investing in development and design is one of the more expensive ways for a company to increase returns. Plus, Amazon are in such a dominant e-commerce market position [0] that they don't need to worry about UX beyond the ability to click "buy". Despite the poor design, their share is forecast to continue growing past 40% this year [1].
Yes but in arguing that you miss the point entirely. If Amazon's only motives in how it designes its customer interface are "hah, who gives a shit, we're so big that they'll keep buying even if we mistreat them and expose them to rampant fraud", that speaks of a shitty company which will eventually be eaten by the market. Consumer tolerance is finite, and smarter people than me have noticed the same thing and are working to chip away at it with shoppers.
I'd also hope for something a little bit more honest from Amazon, given all their multi-decade spiels about customer service, but here we are.

Agreed! Although "eventually" takes a very long time, possibly decades. In the meantime there are a host of cheaper tactics for maintaining and draining market share: acquisitions, exploitative terms (like Amazon's "best buy" conditions), regulatory capture etc... .
The issue is that the current system of shareholder capitalism strongly encourages short-term gains in lieu of sustainability. It's very difficult to justify spending on ease of use when you already have the users and there are things you could do to milk them like making ads more subtle.
