Courts have generally interpreted the customer-welfare aspects of the Sherman Antitrust Act as meaning “customer, as opposed to business”, rather than “customer, as in the one making the purchase”. Courts have generally not been bothered when one corporation screws over other corporations if there’s no demonstrated harm to non-corporate entities in the marketplace. The Sherman Antitrust Act wasn’t intended to protect corporations from being out competed, and no corporation has a right to their business model being viable. Corporations screwing each other over so that they can provide the best possible experience for non-corporate members of the market is exactly the “competition” that the act was devised to encourage.
