Original title: Cook: AppleTens of billions of dollars in research and development, 30% commission is the right source: PingWest games

Apple CEO Tim Cook testified for the first time in the Epic Games v. Apple monopoly case on Friday, local time. Mr Cook said, Epic Games's move last year to bypass the 30 per cent commission Apple charged on its popular video game Fortnite was "malicious" and Apple removed the app directly. In addition, when questioned by Apple's lawyers, Cook pointed out that Apple has invested tens of billions of dollars in research, privacy and security, which is why Apple charges a 30% commission on apps and in-app purchases.
