Tell them what exactly? That's a case of a developer not wanting to continue maintaining an app on the platform. And thankfully WINE and Proton are able to pick up the slack and make the game playable without the support of the devs. Epic still wants to publish Fortnite on iOS, presumably, and in the meantime there isn't a way for them to do so without returning to the 30% cut.
