If Apple did not retain such tight control over iOS app distribution (and considerably looser controls over Mac app distribution), then they would still have a moral obligation to help their customers defend against malware. And this application is definitely close enough to being malware that Apple would have to assess it as a potential threat and at least consider the possibility of blocking it.

You can't exclude Apple from having to make a judgement call here unless you want Apple to be thoroughly hands-off about security and privacy concerns to an extent that was really harmful to Microsoft's reputation back when they weren't taking security at all seriously.
