Not a good argument for the tiny fraction of smartphone users who happen to use iPhones, or not a good argument at all?

The comment I replied to mentions the iPhone, but made the blanket statement "Your mobile..." plus the article I linked to addresses multiple mobile OSs.

It would be helpful to explicitly state which make and model smartphones you believe are not susceptible to baseband threats. I think Blackphone has also integrated countermeasures but information on this topic is pretty sparse.
