These two options are not logical.
1 - well, this action makes no sense at all.
2 - But here you are very mistaken. If there is a prohibition, it is always clearly stated. There are 2 genres: erotica and porn. They may ban either porn or porn and erotica. But Ocean turns out that porn is prohibited, but no one has banned erotica. Why then does he remove some of the erotica and leave some behind?
These are not options or alternatives, these are bits of information that might help explain why not everything is being cut - Ocean is doing the bare minimum to meet the terms he has to.
The problem is that the prohibition was added while Ocean had a license - once his license expired, he couldn't relicense the music without cuts. Terms and conditions change all the time, and it usually takes effect on renewal.
Have you ever looked into music or sound effects licensing? It's pretty convoluted, especially since all these licnesing aggregator companies popped up. Consider that if the licensing company is located in Iran, it might have stricter terms than one based in the Netherlands. Then there are the terms of the content owner, who puts it up - they might have strict terms or the might have none. What often happens is new creators make it available for everything, and once they start finding out their music is used in porn, they get upset and change the terms. The companies that do this licensing are often of drifting between regulations by making up their own terms on the fly and having clauses that seem fair, but really allow them to reserve their rights in any situation.
So Ocean who bought into a subscription license, finds on renewal the terms are changed. Or the creators say he breached the terms, because they didn't realise anything ment porn. It's all out of Ocean's hands because the legal fees are higher than the price of licences.
So he's done the pragmatic thing and tamed down season 1 just to keep the ball rolling.
I don't see why this is so strange to understand. It could be anything. Sound effect companies have issues with making squeaky toys with their sound effects, creating sample libraries as derivative works are a nono etc. Sync licensing is brutal, but it's about the only way musicians make any money at all these days.
