It's not a conspiracy, if there is an avenue through which porn could make it onto their platform and Apple has control over that avenue it will be closed. In software, in hardware or through the TOS and a review process. You can count on it.
A web browser allows porn on your platform. So Apple has failed since the launch of the iPhone to do this. A Developer creating an app that plays Side-by-side 3d Videos is perfectly allowed by ToS.
I have porn on my iCloud Drive, photos, even within certain apps (well... adult but not porn. at what point does someone sending you a photo change to porn?), and through the browser.
This is factually untrue.
While the puritanical nature of the App Store is weird, particularly when they have no issue with drug and sex references in their keynotes. You are way off.
