Once again, Apple will very clearly appeal this ban. Therefore, this may not persist. However, if it does so, it will have a huge impact on the entire mobile industry.

Apple is not the only company that Epic is targeting. Google has a very similar policy for the Google Play store, including the same 30% reduction in all payments. Fortnite is also currently not available in the Play Store, although unlike the iPhone, it can easily be side-loaded or installed from a third-party store (such as the Galaxy Store).
