Before anyone jumps to conclusions, all this ruling means is that this example of an iOS virtual machine (for the purpose of security research) counts as fair use. It doesn't exactly open the doors for everyone to run iOS in virtual machines.
From the ruling[0]: > As to count one, we agree that Corellium is shielded by the fair use doctrine. First, Corellium’s virtualization software is transformative—it furthers scientific progress by allowing security research into important operating systems. Second, iOS is functional operating software that falls outside copyright’s core. Third, Corellium didn’t overhelp itself to Apple’s software. And fourth, Corelli…
> The important part here is that it proves Apple does not have the defacto right to claim infringement on iOS. If your emulator is transformative, offers functionality beyond default iOS, doesn't abuse their services and doesn't threaten the iOS market (eg. iPhones) it should be considered lawful.
You are describing fair use. This isn’t establishing the precedent you think it is. Corellium said “hey, what we are doing is fair use” and the court agreed, describing why it was fair use.
