You can find this in Epic's filing. As you point out, Epic's federal antitrust claims were not as well received as their claims based on California law at the temporary restraining order stage, but they have not been finally resolved. https://cdn2.unrealengine.com/epic-v-apple-8-17-20-768927327...
> Apple conditions app developers’ access to app distribution through the App Store on their agreement to use Apple’s IAP to process all their customers’ in-app purchases of in-app content ... Epic is likely to prove that this conduct is: (a) tying per se; (b) an unreasonable restraint of trade under Section 1 of the Sherman Act under the rule of reason; (c) unlawful maintenance of a monopoly under Section 2; and (d) a denial of access to an essential facility under Section 2.
This is a quote from the letter that Apple sent to Epic;
"If your membership is terminated, you may no longer submit apps to the App Store, and your apps still available for distribution will be removed. You will also lose access to the following programs, technologies, and capabilities:"
"- Engineering efforts to improve hardware and software performance of Unreal Engine on Mac and iOS hardware; optimize Unreal Engine on the Mac for creative workflows, virtual sets and their CI/Build Systems; and adoption and support of ARKit features and future VR features into Unreal Engine by their XR team"
That is a statement that Apple made saying they will stop all help they give to Epic getting UE running on all Apple hardware. With the other stuff in the letter it makes it very clear that the problem is not just one for Epic Games, but all of Epic.

> Apple has never used signing on Macs to block specific policies
This is literally what Epic just filed an injunction over. They're being blocked from Mac tools because of a dispute over payment methods, not because anyone thinks that Unreal Engine is literally malware.
> - Access to provisioning portal for certificate generation, and provisioning profilegeneration
> - Access to Developer ID signing certificates and Kernel Extension signing certificates
Yes, people have been saying this since 2011, and an important component of that fact is that within the past few weeks, Apple did it.
Epic is fine with the appstore, but it wants to handle it's own in-app payments. You can have an app store with a separate in app payments; Uber does for example. Epic says as much in it's argument for a preliminary injunction.*
Stadia is actually more of an existential issue than Epic because they want to run unapproved games.
According to the court filing, Apple is denying Epic access to any development tools, software betas, APIs and the like. Epic will not be able to keep Unreal Engine up to date. Including on MacOS.
The end result will be that Unreal Engine, and all applications developed with it will be dead in the water on MacOS/iOS/iPadOS.
From the the legal filing:
>... when Epic sued Apple to break its monopoly on app stores and in-app payments, Apple retaliated ferociously. It told Epic that by August 28, Apple will cut off Epic’s access to all development tools necessary to create software for Apple’s platforms—including for the Unreal Engine Epic offers to third-party developers, which Apple has never claimed violated any Apple policy. Not content simply to remove Fortnite from the App Store, Apple is attacking Epic’s entire business in unrelated areas.
>Apple stated that unless Epic capitulates, Apple will also block “[e]ngineering efforts to improve hardware and software performance of Unreal Engine on Mac and iOS hardware [and] optimize Unreal Engine for the Mac for creative workflows”.
Epic is not saying that Apple is removing gams that rely on UE. (https://cdn2.unrealengine.com/epic-v-apple-8-17-20-768927327...)
What Epic is saying that they will no longer be able to make any updates to UE, which will effectively kill it as a viable business.
