Now, I agree, search is also governed by algorithms - but I'm also quite capable of sitting there for a few minutes, paging through until I get past them to find what I want. I do not want anything controlling my filters, except me. Edge cases can be dealt with. Latex lovers need to learn that it's a text editor first.
As for Amazon, I have never found their recommendations helpful, or bought anything via them. If Amazon wants to help me, it really needs to clean its house on fake recommendations, and bogus products.
