Selling things is selling things. That isn't vertically integrating. A good example would be selling and shipping now that Amazon is getting into delivery as well.

Amazon ships more packages through its DSPs than anyone. But I don’t see them doing delivery as anti-competitive. It is highly integrated and streamlined however.

They put a absolutely massive amount of resources on solving delivery. And they probably do it better than anyone. You couldn’t split that out without totally breaking it.
