What's wrong with porn? I know there will be plenty available through the browser anyway but it seems odd for an OS vendor to be in a position to take a puritan stance.
The problem with not allowing for 'edge cases' is that a lot of popular software probably started as a weird 'edge case'.

Except there won't.
Imagine:
1. No third-party browsers.
2. No non-whitelisted sites viewable in the default browser (except maybe in "legacy mode", meaning no scripts, no videos and the browser censors the text.)
3. If you're lucky, there will be an "adult mode", where you can access URLs with adult content (but the "guardians" will be notified of each URL in real-time, along with your name and address. Not the NSA, and not in secret, but one of the filtering companies we know today. And everyone living in the same street as you will get a "Warning! pervert in neighbourhood!" alert.)
