I think you're confusing search intent with discovery intent.
Of course Netflix isn't going to stop showing you movie options when you're trying to discover something new. If the user doesn't intentionally know what they want to watch, they need to continually see content to discover it.
And Amazon search isn't terrible because of a price-hiding scheme, it's because they have a terrible UI company-wide, from the Kindle to EC2. People typically aren't browsing Amazon to discover new products - they search and move on. Are you suggesting that Amazon search should be an internet price aggregator too?
It seems like you're playing the Halloween music early by saying these companies have terrible UX as a complex ploy to keep you engaged while not giving you what you want. The reality is that they have wide userbases which are fickle to UI changes, and it takes time and research to roll out anything new.
Amazon may not be intentionally malicious. When you make decisions only on a metric like sale conversions, you will be optimising other factors you are not even aware of. Nothing necessitates that the best UX and happiest customers will be the most profitable.
For example, I recall a story about Amazon trialling infinite scroll. It had positive customer feedback and users viewed more products compared to pagination. However, sale conversions dropped so obviously it was never rolled out. Was it a better browsing experience? Possibly, but that isn't the metric Amazon is optimising for so it just doesn't matter. I expect that there is a threshold where any time saved for a user searching Amazon is not spent buying more products from Amazon but spent on competitor sites.
Missing design targets because you're optimizing on the wrong metrics is a real problem - but for Amazon to be unintentionally making their search so overly complex to keep users bogged down (as you say) it would require them to be optimizing on number of searches, not sales conversions or revenue.
I think even you can admit that sounds just a little absurd.
They will optimise for probability of a search leading to purchases and likely see 5s searches leading to fewer purchases than 90s searches.
You get the same phenomena in retail. You get intentionally confusing layouts in shops, hidden exits, difficult placement of essentials and related items spread at different ends of the store, no clocks etc. to maximise the amount of time a customer spends in their store. It works.
