Well, it's a bit more interesting then that because it's not Epic Games who made and owns Unreal, but Epic Games International, which Apple had a separate contract with, but EGI shares Epic Games' assets, contact details, website, etc.Let's see if I've got this right:
Basically the court ruled that Apple can't revoke Epic's access to the dev tools needed to maintain work on the Unreal engine because Epic violated no ToS regarding that and they can't just revoke access to the tools just because Epic pissed them off.
At the same time the court is basically telling Epic that they're probably pretty fucked on the Fortnite end of things as they knowingly violated ToS leading to "self inflicted wounds" that are nobody's fault but their own.
I wonder if the fact that Sweener asked Apple for a ToS exception before intentionally fucking up can work against them in court.
So it led to the interesting case of Apple not being able to prove Epic Games owned Unreal.
Isn't law fun?
