They are however required by law to allow other app stores to function. This new licensing cost is a bald faced attempt to make other app stores nonviable. I'd be highly surprised if the EU is okay with that.
In my view, they are making alternative app stores way more attractive to FLOSS apps, because they will incur no fees from Apple, and the creators won't have to set up an NPO.
Edit: Seems I misunderstood, I just re-read the relevant section:
>iOS apps distributed from the App Store and/or an alternative app marketplace will pay €0.50 for each first annual install per year over a 1 million threshold.
The fact that they are charging money for apps installed from non-App Store sources is ludicrous to me, if they aren't running the store, then they don't get to collect fees on it, imo.
