Developers sue Apple over iCloud

On June 30, 2025, Proton filed a complaint in federal court in California along with other international developers to demand that Apple allow real competition in app distribution and payment methods within iOS. The complaint alleges that the current App Store system particularly penalizes services that rely on subscription and privacy models, forcing them to pay commissions of up to 30% on their revenue just for using Apple's payment system.

According to Proton and the other plaintiffs, Apple keeps access to alternative app stores blocked and prevents developers from informing users of cheaper payment methods outside the official platform. In addition, the Cupertino company retains his position as gatekeeper by imposing technical restrictions that prevent competing apps from functioning fairly, for example, by prohibiting tools like Proton Drive from running in the background like iCloud does.
