> I once wrote reviews for Amazon until I thought better of it.

I don't write reviews on Amazon to make Amazon better. I do that to let other people know of a good or bad product, so they can make a better buying decision than me. And I too appreciate when other people tell me when some product is amazing or crappy. Amazon just sells most of the products available for sale on the internet. So no wonder it collects reviews. But reviews is not what Amazon sells. It's just a byproduct.
