Apple doesn't allow porn apps and provides no way to side load. That's 1.3 billion people who are effectively being censored. And before you say you can still watch videos there are apps that do things videos don't. 3D games, real VR, etc... Apple has a whole list of things you aren't allowed to have in apps.
In a cool world, Apple would have an optional, unmonetized un-curated community app store that allows everything but criminal facilitation, is scanned for malware, and possibly requires open source.
