Tim Sweeney, CEO of Fortnite developer Epic Games, has criticized Apple and Google for having an "absolute monopoly" on their respective app stores. He especially slammed the 30 percent cut on in-app purchases and transactions.

"Apple has locked down and crippled the ecosystem by inventing an absolute monopoly on the distribution of software, on the monetization of software," Sweeney said in an interview with CNBC over the weekend.

"If every developer could accept their own payments and avoid the 30 percent tax by Apple and Google we could pass the savings along to all our consumers and players would get a better deal on items. And you'd have economic competition," Sweeney was quoted as saying.

Claims That Google Is Stifling Competition

Epic previously made Fortnite available to Android devices not by offering it on the Google Play Store but through a launcher on the Fortnite website that downloaded the game. This helped the company avoid a 30 percent cut on app stores by making the game available as a "side-load" install. Fortnite finally arrived on Google Play Store earlier this year upon users' requests.

"Google intentionally stifles competing stores by having user interface barriers. It also includes obstruction to installation, by stifling competition and payment. To finally have competition among stores, other stores need to be able to exist and thrive on these platforms," alleged Sweeney. Both Apple and Google did not comment on the report.

Apple's Strict Guidelines

Last year, the company released Epic Games Store for Windows and Mac PCs and incentivized game makers by taking a comparatively lower 12 percent fee from sales. The Store is yet to arrive on iPhones because Apple has strict guidelines in place, which prevent competing software stores.

Earlier this month, Sony announced a strategic investment of $250 million to acquire a minority interest in Epic Games. Fortnite is the world's largest game with over 350 million accounts and 2.5 billion friend connections.
