How does cleaving companies apart into their separate unrelated businesses address monopoly practices or anti-trust issues? If Amazon has a monopoly on delivery, the parted-out delivery company will still have a monopoly on delivery. If AWS has a monopoly on cloud computing, making AWS independent changes nothing. AWS is not going to begin competing with Amazon's last-mile delivery business if the two are split off into separate companies.

If nothing else, it could prevent Amazon abusing its monopoly, by leveraging its monopoly in one area to slap competition around in other areas.

Amazon uses its cloud revenue to significantly undercut competitor prices, then raise prices again after they go out of business.

Splitting these two will cause Amazon Products to be actually profitable.

The platform also uses its position to push their products, products they made after gathering data of items sold on their platform.

At the very least, Amazon shouldn't compete with their own customers (i.e. Sellers)
