Anti-competitive behavior doesn't become a violation of US law until it involves the abuse of a monopoly position, involves market collusion, or breaks some other law. While anti-competitive, Apple doesn't currently exercise a meaningful monopoly in mobile device operating systems: either one looks at handsets where they are actually not even the market leader or one looks at tablets which is hardly a developed market. Apple's actions with regard to the Agency Model aren't prosecutable because of any Apple monopoly but because it involves market collusion. Now, if Google and Apple colluded to prevent eBooks from being sold on mobile OS marketplaces without a 30% cut, THAT would be prosecutable.
