How does it benefit society that non-Amazon sellers have to either use their competitor's infrastructure to compete with them on sales, or build their own infrastructure while attempting to grow on an unknown platform? Amazon's infrastructure may be meritable, but leveraging it to compete with their own customers is not.
> And further, I don't think explaining away a corporation's dominance by using monopolistic practices is very convincing when they rose to power so recently: how did Amazon get so big in the first place?
So you think that 25-year-old companies can't be monopolies?
> Also, most of the monopolistic practices, of the kind that would allow a company to maintain dominance in spite of merit, are things Amazon is not doing.
Let's I produce and market a product, i.e. the Iron Gym pull up bar that goes in your door frame. I start selling it on Amazon. Amazon then leverages their platform to identify successful products, identifies my Iron Gym pull up bars are successful, creates an Amazon Basics pull up bar that's identical, and uses their platform to boost their pull up bar over mine. So I take all the initiative, do all the work, and take all the risk, and once I show that I have merit, Amazon swoops in and takes all the rewards. How is that not maintaining dominance in spite of merit?
This is just one case. There are many.
> It's monopolistic practices are limited to it's own platform.
And what a limitation that is, being limited to the largest online sales platform in the world!
