After bad reviews for Microsoft promoting the Microsoft Store, creating a closed platform for developers, Epic Games CEO Tim Sweeney has put up with Apple and Google.
Both have created app stores based entirely on the idea of a monopoly, Sweeney said, noting the 30% fee developers have to pay Google and Apple to sell their apps.
In an interview given to CNBC, Sweeney reports that the extra charges that developers have to agree on only increase the price of apps and games. Apple has invented what Sweeney calls an "absolute monopoly", while Google does not leave competing stores with "UI barriers".
Epic Games previously released Fortnite for Android, one of the most popular mobile games, as a standalone APK installer to avoid the 30% fee Google asked for to make the game available through the Play Store. However, the game was eventually released on the Play Store after Sweeney admitted that downloading it manually was a very complicated process for some of its users.
"Google is deliberately suppressing competing stores by blocking the user," Sweeney told CNBC.
"If any developer could accept the amount requested without adding a 30% from Apple and Google, we could pass the discount on to all our consumers."
Sweeney's company created it Epic Game Store last year, with developers paying a fee of 12 percent.
"Apple has locked in and paralyzed its ecosystem by inventing an absolute monopoly on software distribution, and software revenue generation," Sweeney said.
Next week, representatives of various technology companies, such as Apple CEO Tim Cook, will attend a congressional hearing on the anti-competitive methods they use.
