> What am I missing here? To my knowledge NSO software (and similar) target exploits in OS-specific applications (think default Messages app on iOS) rather than, e.g., Google Voice. That being said, I personally don't know if Google Voice and similar are special enough not to have their own exploits (spoiler: they probably aren't, and Google Voice in particular would be a very enticing target). I'd expect there's more to it than that, though. I'm really not familiar with these exploits.
