Apple is determined to take a slice of in-app purchases, no matter how users access apps or make their payments, it seems. After dropping commissions to 27% following a court ruling that said Apple had to allow app developers the ability to point to their own payment options via the web, the company is now floating the idea that it could take a similar course of action for apps that are downloaded outside its App Store.

In the EU, Apple will be subject to a new law that will for the first time allow users to download apps to their devices without having to go through the App Store — a major change that will impact how iOS apps are discovered, marketed, and accessed. Apple has staunchly argued against such a measure, saying that it will expose iPhone users to numerous security risks, similar to Android, which already permits the practice.
