They breached their contract with Apple, then filed a lawsuit against Apple and launched an anti-Apple marketing campaign. Apple has every reason to cease doing business with them.
This. While I agree that the 30% cut that everybody takes is likely too high, there is no way I'm ever going to side with Epic here. You knowingly signed terms to be on the App Store with a well established cut being taken on the platform (and every other platform), then you knowingly tried to slip in a update to circumvent that and got banned. Then you (which was probably the plan all along) launch a smear campaign of sorts against the company, and expect them to just reverse the decision and raise your cut? Fuck you.
Do the people that are siding with Epic not realize that they are simply trying to act innocent, and like the good guys because they simply want MORE of your money? Or is this simply because people think it's cool to hate on Apple? They hit it bit with a game, and are now even more money hungry then before. This isn't about getting Apple to open up their ecosystem (don't forget that they are suing Google as well), this is simply about them not wanting to have to give up a cut of the money they make off of you. People will shit on Apple for almost everything they do. Apple doesn't need Fortnite/Epic, and Epic sure as hell needs Apple.
If this somehow ends on Epic's side, then they will go after Microsoft, Sony, and Nintendo next.
