Facebook reportedly preparing to file antitrust suit against Apple SHARE Facebook Inc. is preparing to file an antitrust lawsuit against Apple Inc. for alleged anticompetitive behavior, according to a report today by The Information. The report, which cites anonymous sources, said the antitrust lawsuit, should it go ahead, will allege that Apple is forcing developers to follow App Store rules that Apple’s own apps do not have to follow. The complaint may also allege that Apple’s refusal to allow third-party apps from becoming the default messaging services on iOS devices instead of iMessage is also anticompetitive. Another aspect of the potential Facebook lawsuit could include Apple forcing developers to use Apple’s own in-app payment services. Should Facebook argue that in a lawsuit, it would follow in the footsteps of Epic Games Ltd. which filed an antitrust lawsuit against Apple in August claiming that the forced use of Apple’s payment services was also anticompetitive.
