SAN RAMON, Calif (AP) — Apple CEO Tim Cook will take the witness stand on Friday in a high-stakes courtroom battle. Cook will be testifying in a trail over the lucrative commissions that the iPhone maker has been raking in from Apple’s mobile app store that has become a cornerstone of its $2 trillion empire. The maker of the popular video game Fortnite is trying to prove Apple’s 15% to 30% commissions on transactions in iPhone apps are part of an illegal monopoly. The timing of Cook’s highly anticipated testimony was confirmed Wednesday when a federal judge granted Apple’s request to allow the executive to be the first witness sworn in Friday during the trial in Oakland, California.
