That does tell us something about the corporate structure though - whilst a lot of people think AWS would be better off being spun out, there's no way you hire the head of AWS as CEO of Amazon if you think that's the direction forward.
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.
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.
Amazon is huge... but Walmart is truly massive... over double Amazon's size in just about every metric. They clearly have the resources to handle things on their own.

(6000 employees in 2018, per wikipedia)
Walmart doesn't have the same capabilities. Being larger doesn't mean they can do it.
The case of Amazon using internal market place data to guide their own product strategy has already been made over and over, so the precedent exists.
