Apple has criticised the availability of a pornography app on iPhones in the European Union, blaming the Digital Markets Act (DMA) for undermining consumer trust. The regulation, which took effect in 2022, forced Apple to permit alternative app stores, leading to the distribution of an adult content app called Hot Tub via AltStore.

Apple expressed concern about the safety risks posed by such apps, particularly for younger users. AltStore, which received financial backing from Epic Games, stated that Apple's notarisation process approved Hot Tub. Apple, however, dismissed this claim, insisting that EU rules compelled it to allow the app but that it would never have accepted it in its own store.

Epic Games' CEO defended laws like the DMA, arguing that Apple had previously abused its control over competing apps. Despite its support for AltStore's expansion, Epic Games clarified that its own app store in the EU does not carry the Hot Tub app and has never hosted pornographic content.
