Tim Cook and Apple don't know how profitable their app store is, but fear not Tim Cook "has a feel, if you will"

Apple CEO Tim Cook finally took the stand during today's block of the Epic Games v. Apple trial, fielding questions about App Store curation, profit, and policies as Epic Games attempts to prove to the court that iOS is anticompetitive to the point that the legal system needs to step in. Since much of Epic's accusations deal with how Apple conducts business through the App Store, Cook's testimony as Apple's boss is a crucial moment in a weeks-long trial that could have significant ramifications for digital storefronts that sell games and apps.
