ECONOMY: HOW APPLE HAS ABUSED ITS MOBILE
PLATFORM DOMINANCE
Shili Shaot
ABSTRACT
Apple's iOS smartphone platform wields de facto monopoly power thanks to its
dominant revenue share and Apple's sticky product ecosystem. Apple has abused this power
to tie the distribution of digital goods on iOS to its proprietary in-app purchase payment
system to impose a 30% tax and extract supracompetitive profits. Moreover, Apple has
blocked rivals and favored its own apps using its control of the App Store, distorting
competition both on the iOS platform and between smartphone platforms. Courts today are
increasingly hostile to lawsuits against dominant firm behavior, however, creating doctrinal
obstacles that impede antitrust enforcement against tech platforms such as Apple.
This Note makes the antitrust case against Apple and explores why features of consumer
tech platforms Apple represents demand a reform of the current antitrust regime.
