The companies claimed Epic violated their guidelines by announcing a way for players to buy in-game currency outside theirproprietary payment systems.
iOS purchase flow on left, Android purchase flow on right. The question is, who's going to blink?
Apple set the standard for mobile software pricing when it launched the App Store in 2008. Android users can download the app from other app stores, although that's generally not an option for iPhone users.
Fortnite consists of 100 players skydiving on to an island and engaging in one-on-one combat until a single player is left standing.
Facebook is also among the companies that are stuck with Apple's 30 percent commission.
Facebook joined the growing ranks of companies publicly complaining about the 30% fee that Apple collects on payments made through its App Store. When purchasing items or V-bucks in Fortnite Mobile, players can now choose between the built-in payment system and a new Epic direct payment, which links out to the Epic Store.
The move has garnered industry support, with a Spotify spokesperson saying in a statement: "We applaud Epic Games' decision to take a stand against Apple and shed further light on Apple's abuse of its dominant position". That gets Epic 10 percent more money from each transaction even with the discount.
Just earlier on today, on the 13th of August, Epic games had added an update to the game, which allowed both Apple and Android users to pay Epic directly to the company instead of what was allowed and appropriately required.
This plan could backfire for Epic, though. On Android, it says, "Facebook doesn't take a fee from this purchase", while on iOS, it says, "Apple takes 30% of this purchase".
Epic is not the first to sue over the App Store.
Fortnite was removed from the App Store and then the Play Store on the grounds that it did not comply with the policies. That could change at any time, though. "Epic carries this suit to end Apple's uncalled for and hostile to serious activities that Apple attempts to unlawfully keep up its imposing business model in two particular, multibillion-dollar markets: (I) the iOS Application Circulation Market, and (ii) the iOS In-Application Installment Preparing Market (each as characterized underneath)".
