Is Epic Games’ showdown with Apple turning into a mismatch?

If Epic Games hopes to dismantle the fortress surrounding Apple’s iPhone and its app store, the video game maker probably will need to roll out some heavier artillery heading into the second week of a trial threatening Apple’s $2 trillion empire.

So far, at least, Epic has been having trouble proving its allegations that the iPhone maker’s 13-year-old app store has turned into an illegal monopoly.

Epic, the maker of the popular Fortnite game, contends Apple has been gouging app makers by charging commissions ranging from 15% to 30% for in-app transactions because it forbids other options on its iPhone, iPad and iPod.
