Yes. And if lower prices are the only reason for antitrust everything is fine.
In the US at the beginning of the 80s Robert Bork broke from the traditional antitrust thinking and started a tradition where only "consumer welfare" (lower prices) are meaningful reason for antitrust policies.
Rest of the world never bought that and now thinking even in the US is starting to change. Free markets are not just about low prices. Restoring traditional antitrust and competition policy principles are coming back. Such as applying common carrier obligations and duties to platform economics.
