The other apps are clients. The apps themselves don't actually contain any content, they're just code. An app that itself contains an offline copy of a book with NSFW text is not the same thing.

Meanwhile Reddit is a doubly poor example because even though the service contains NSFW content, it marks it as such, and then the client not only doesn't itself contain it but gives the user a separate opportunity to select against it when using the app to download pages.

Bible apps often don’t contain the text directly, but allow the user to download a preferred translation on initial startup. That didn’t prevent them from being marked NSFW.

And clearly that wasn’t the standard anyway. Before the introduction of the policy restricting religious texts, the only apps F-Droid had marked NSFW were frontends to porn sites, even though the apps presumably contained no sexual content directly.

It should be pretty obvious why porn apps are marked NSFW despite not containing any content. Substantially all of the content they can be used to access is NSFW, whereas it's reasonably possible to access only SFW content on Reddit.

Which would also explain the Bible apps without an initial copy. Choosing which translation to download when substantially all of them are translations of the same NSFW text means that substantially all of the users would end up with NSFW content on their device by using the app.

I would still say that counts as the app providing the content, not users. It's not user uploaded, it's app uploaded.
