IPhone owners can sue Apple for monopolizing App Store, Supreme Court rules
Justice Brett Kavanaugh, in the majority opinion, said that when "retailers engage in unlawful anticompetitive conduct that harms consumers," people buying those companies' products have the right to hold the businesses to account.
"That is why we have antitrust law," Kavanaugh wrote. The court's four liberal justices joined Kavanaugh in the 5-4 decision.
The Supreme Court opinion notably does not accuse Apple of violating antitrust law: It holds that consumers have the right to sue the company for monopolistic behavior, because they purchase apps directly from Apple.
