アップルは App Store で販売・配信するアプリに対して、有料アプリ自体の売上の30％を手数料として徴収するほか、機能の有料アンロックやゲームのアイテム課金などについてもアプリ内購入の利用を義務付け、決済ごとに売上の30％を得ています。
Epicはこの30％の「ストア税」に対して、個別の審査コストやアップルに負担がないゲーム内通貨の購入でも毎回30％を徴収するのはおかしい、決済手数料としてはクレジットカードやPayPalなどネット上で使われている決済サービスの10倍近い暴利であり、アプリ配布に App Store 以外の選択肢がなく決済サービスとして必ずアップルのアプリ内購入を使わざるを得ない状況でこの手数料は独占的地位の濫用であると以前から非難してきました。
Apple removed Fortnite from the App Store and has informed Epic that on Friday, August 28 Apple will terminate all our developer accounts and cut Epic off from iOS and Mac development tools. We are asking the court to stop this retaliation. Details here: https://t.co/3br1EHmyd8
“Today, Epic Games took the unfortunate step of violating the App Store guidelines that are applied equally to every developer and designed to keep the store safe for our users. As a result their Fortnite app has been removed from the store. Epic enabled a feature in its app which was not reviewed or approved by Apple, and they did so with the express intent of violating the App Store guidelines regarding in-app payments that apply to every developer who sells digital goods or services.
"Epic has had apps on the App Store for a decade, and have benefited from the App Store ecosystem - including it’s tools, testing, and distribution that Apple provides to all developers. Epic agreed to the App Store terms and guidelines freely and we’re glad they’ve built such a successful business on the App Store. The fact that their business interests now lead them to push for a special arrangement does not change the fact that these guidelines create a level playing field for all developers and make the store safe for all users. We will make every effort to work with Epic to resolve these violations so they can return Fortnite to the App Store.”
