Apple v. Epic trial wraps up as judge spars with Tim Cook

Apple CEO Tim Cook testified as the final witness in the Apple v. Epic Games antitrust trial on Friday, and the poised executive faced a tough round of questioning from the federal judge Yvonne Gonzalez Rogers.

The questions were pointed and gave a rare window into the thinking of YGR, as the judge is frequently referred to, about arguments offered during nearly three weeks of testimony. The 10-minute round of questioning was important because Gonzalez Rogers, who presides over the U.S. District Court for Northern California in Oakland, will decide the case in lieu of a jury.
