This is their business. This is how they want to run it. We can either boycott them or not. I have worked most of my life in mega big corporations, and I cannot say "oh I didn't know that bankA did this and bankB did that". I am either stupid, complicit or indifferent.

Amazon will look after Amazon's interests (aka the shareholders). The little people have rights defined by laws. As long as they are not breached, Amazon (and every Amazon out there) will match on.

To avoid any misunderstanding, I do not condone the majority of Amazon's practices and thus I don't buy from them (or at least they are low in my list of preferred options). But since we got capitalism, and since the US is the HQ of capitalism.. then why is anyone surprised? Facebook will spy. Amazon will squeeze every cent they can, and so on..
