FWIW, single data point, YMMV, etc., but where I work (under AWS) I have never seen behavior that is exploitive of the customer like you're talking about to be encouraged or allowed.
Yes, AWS may be different from how things are done in retail, and we're huge so I'm sure it does happen here and there -- but from my admittedly limited vantage point, Bezos' heavy emphases on long-term thinking and earning the customer's trust have taken deep root everywhere I've been able to see.
Doesn't mean peeps always get it right, some choices are difficult, compromises have to be made, there are outliers, etc., but still, it's there. I've just never seen cheap thinking around customers, so to speak, and I really like that aspect of working where I do.
If that ever changes in a broad way, that'll be the beginning of the end of Amazon's dominance.
