Yes, the very reason for Apple to create the "store-in-store" concept was that they thought that the buying experience for their products was inadequate (both in presentation of the products and qualification of the staff): https://web.archive.org/web/19990210163227/http://product.in...

The Amazon storefront simply seems to be an extension of that concept from brick and mortar to online stores. I'm not sure what's supposed to be unlawful or unethical about this.

I think the difference is that Best Buy retail stores are not a marketplace, there are no third-party sellers in a Best Buy.

In fact, there are, as in much of Big Box retail.

There's store-within-a-store, but it's not really the same thing as a marketplace, and not the type of thing where any provider dominates the market enough to have a monopolistic power on it.

A large part of what you see on shelves are not the retailer's, but are on consignment from the manufacturer.

The manufacturer also pays for the product to be displayed, with different rates for different positioning.

The limit is physical space on the storefront, and that's a problem that Amazon doesn't have.

Consignment in retail is more of an inventory accounting arrangement. Marketplaces are much more open and allow sellers to set their own terms.
