> they take a lot of 'short term losses in exchange for trust' decisions

I'm sorry, but I don't believe your statement. They're not doing enough about fake reviews, and definitely aren't doing enough about poor quality products, fake products, and poor products squatting over good / brand products. Their marketplace is not curated enough, and buying a product is a gamble.

There are a few posts about that; one I remember is that someone bought a book off Amazon, but got a fake / copy / low quality reproduction instead.
