Rakuten

Telegram, the messaging app, filed a formal antitrust complaint to the EU over Apple’s App Store. The company joins Spotify and Rakuten in complaining the app store represents a monopoly power, given that developers have to accept Apple’s terms, including a 30 per cent commission on in-app purchases.
In its complaint, Telegram took issue with Apple’s argument that the App Store commission keeps it running. Pavel Durov, Telegram founder, stated "Every quarter, Apple receives billions of dollars from third-party apps. Meanwhile, the expenses required to host and review these apps are in the tens of millions, not billions of dollars. We know that because we at Telegram host and review more public content than the App Store ever will".
