They can release updates and bug fixes on the macOS platform by removing the native payment feature they included that tries to route around Apple's in-app payment system. Epic broke the rules on purpose and then started a public relations fight when Apple enforced the rules that Epic agreed to when they started developing on Apple's platforms. They are in no way a victim; that's a hilarious idea. This is all part of a deliberate strategy born from their desire to not pay Apple the cut that every other developer on the platform pays. You can argue that Apple's cut is too high, but that isn't germane to this issue. Apple's cut is a tradeoff you make in order to have access to the large audience of Apple users.
If you're a landlord and I rent your apartment and you tell me that I can't smoke on the balcony and I go ahead and do it anyway, I'm going to face the consequences of breaking that rule. Epic isn't a victim, they are just unsuccessfully trying to use their own enormous leverage to try to make Apple back down.
