Apple CEO Tim Cook says the commissions it charges for developers to sell apps through the App Store are no different to those imposed by competitors and that the company doesn't dominate any market it operates in.
The highly anticipated event will hear testimonies from the CEOs of the US's biggest tech platforms. Besides Cook, Amazon CEO Jeff Bezos, Google CEO Sundar Pichai, and Facebook CEO Mark Zuckerberg will need to address questions over concerns their business practices are harming the tech market.
Democrat congressman David Cicilline – chairman of the House Judiciary Committee's Antitrust Subcommittee – recently accused Apple of charging developers "exorbitant rents" that were tantamount to "highway robbery". Microsoft president Brad Smith has also called on regulators to look more closely at app stores.
Cook will argue that the App Store is essentially an enabler of business for developers, offering them a cheaper and superior option to distribute software than those that existed in 2008, when the App Store launched.
"Brick-and-mortar stores charged high fees and limited reach. Physical media like CDs had to be shipped and were hard to update," Cook says.
"From the beginning, the App Store was a revolutionary alternative. App Store developers set prices for their apps and never pay for 'shelf space'."
Amazon's Bezos makes a similar case in his prepared statement, arguing that Amazon has plowed billions of dollars into business failures but also turned up a few successes, such as Amazon Web Services, which have helped grow business in the US and around the world and generated new local employment.
"When customers shop on Amazon, they are helping to create jobs in their local communities," says Bezos. "As a result, Amazon directly employs a million people, many of them entry-level and paid by the hour. We don't just employ highly educated computer scientists and MBAs in Seattle and Silicon Valley."
Cook also points out that App Store commissions are "vastly lower than the 50% to 70%" that software developers paid to distribute their work before the App Store existed.
He will argue that Apple's App Store commissions are consistent with those of most of its competitors and that Apple has "never raised the commission or added a single fee" but rather that it has "reduced them for subscriptions and exempted additional categories of apps".
He says developers keep 100% of revenues they make for the "vast majority" of apps on the App Store.
"The only apps that are subject to a commission are those where the developer acquires a customer on an Apple device and where the features or services would be experienced and consumed on an Apple device," Cook states.
Cook references a study it commissioned and released last week that compared Apple App Store's commissions with cuts taken by Google Play Store, Amazon App Store, Samsung Galaxy Store, and Microsoft Store, as well as marketplaces from Airbnb, Uber, and Epic Games.
The study concluded that Apple's guidelines for in-app purchases are necessary to prevent users and developers from 'free-riding' on the App Store and that all digital marketplaces "routinely forbid behaviors aimed at avoiding fees".
It also points out that "a subscription to Microsoft Office 365 purchased on a computer can be used in iOS apps without Apple collecting a commission."
