Antitrust aside, has there ever been a business reason to split up Amazon? I doubt anyone inside the company ever took that talk seriously.
Probably similar or maybe even clearer than Google since more people understand a store selling their own products than Google owning every single step (with huge non transparent and evidently according to TX colluded margins) in the ad transaction, in addition to all the user data, and their own products.
That is assuming the companies would all be as successful being spun out.
btw, it looks like you have some sort of shadowban. I don't see any terrible comments among your last 20 or so, so you might want to ask @dang if he can look into your case.
