Essential facility
“The term "essential facility" typically refers to physical infrastructure – such as roads, bridges, or power conduits. These are things that cannot typically be replicated easily, and are necessary for the delivery of something.” Sound like Apple’s app store, which can’t be replicated for the delivery of apps on IOS.
“Although the App Store represents a bottleneck to software distribution on the iPhone,” It is not a bottleneck it is a roadblock as it is the only way to distribute software on the IPhone.
“Apple's legal team argued that this doesn't necessarily meet the standard of an essential facility.” I tend to agree that the app store does not meet the standard in itself, but the ability to deliver mobile apps could be. There are really only two OSs out there and it is becoming more and more necessary to have one of them. For example, covid tracking app, hell I could only get into a certain gig before lockdown with a phone as tickets were only sent digitally so had to display from phone. A mobile device is becoming more and more necessary for daily life. Essential maybe not and if not they will be.
“What Epic is demanding is that it be permitted to use the bridge at any time of day at no cost and with no limitations on its terms of access.” I thought Epic is demanding the ability to distribute software and bill on IOS. It is Apple that demand Epic must use Apple’s bridge (App store) to do this. Epic are not allowed to build their own bridge.
As for the Sherman Antitrust law and physical infrastructure did not Microsoft lose a case under the Sherman Antitrust Act, MS software is hardly physical infrastructure.
