I think it just needs to be marketed as a browser for the nostr protocol. They allows web browsers for HTTP and you can find all sorts of bad content that can't be reported or blocked in that regard when browsing that protocol.

It could work 🙏🥺
Apple wouldn’t allow a browser that comes with pornhub as a default tab. In a nostr client the default relays are the default browser tabs. I don’t think Apple would have a problem with users adding their own relays, just as you can visit any website you want.
that's smart actually. might be hard to argue
