Re: Amazon is a shady bookstore
Amazon claims that it doesn't sell anything - it is a "marketplace facilitator" - a conduit, not a vendor. Yes, you can stop chuckling now.
The question is about competition and information. If (company x) becomes a monopoly, does it then acquire greater obligations than it would have in a more competitive marketplace?
I would suggest that it probably does. Given all the gunk that is available on Amazon, I do not believe they decline books based on the truthfulness of the content. Regardless, do you want Amazon to start making those determinations?
If Amazon is serious about being a "platform" it shouldn't act as a publisher. While I am supportive of freedom of association, if you gain monopoly power, but decline to participate in a transaction, perhaps at least you should be obliged to carry an "Amazon has chosen not to stock this product because ...." message at a minimum.
