> Evading antitrust norms via vertical integration is not 'competition'. (Apple app store and 30% rent)

This one is competition though. No one is forced to use Apple or develop for Apple. People purchase Apple because they like their products more than the alternatives.

Apple literally forces you to own an iphone (and a Mac) for you to develop for iPhones. And they also force their users to only be able to install apps through the app store. "If you don't like use an alternative" is not a valid take here.

It is legally.

It really depends on the specifics.

From the Wikipedia entry on vertical integration[1]:

>Vertical integration can be desirable because it secures supplies needed by the firm to produce its product and the market needed to sell the product, but it can become undesirable when a firm's actions become anti-competitive and impede free competition in an open marketplace.

...

>A firm may desire such expansion to secure the supplies needed by the firm to produce its product and the market needed to sell the product. Such expansion can become undesirable from a system-wide perspective when it becomes anti-competitive and impede free competition in an open marketplace.

...

>The result is a more efficient business with lower costs and more profits. On the undesirable side, when vertical expansion leads toward monopolistic control of a product or service then regulative action may be required to rectify anti-competitive behavior.
