Tim Cook plays innocent in Epic v Apple's culminating testimony

But rather than a fiery condemnation of Epic’s shenanigans and allegations, Cook offered a mild, carefully tended ignorance that left many of the lawsuit’s key questions unanswered, or unanswerable.This anticlimax may not make for exciting reporting, but it could serve to defang the dangerous, if somewhat dubious, argument that Apple’s App Store amounts to a monopoly.Epic cries monopoly as Apple details secret ‘Project Liberty’ effort to provoke ‘Fortnite’ banAfter being called by Apple’s own attorneys, Cook took the stand, Law360’s Dorothy Atkins, one of two media members allowed in the court, reported in her comprehensive live tweeting of the testimony. And among the first things Epic’s attorney brought up, when the witness was turned over to him, was the testimony from earlier in the trial by an expert witness that Apple’s App Store operating margins were around 79%.It was not in Apple’s interest to confirm or deny these numbers, and Cook again pleaded ignorance. That said, Epic and other critics of Apple’s App Store fees, which are immensely profitable however the company chooses to obscure it, have arguably already accomplished their goals.
