I can't help but side with Apple on this. I think they'll very soon go "I told you so". My girlfriend is not tech-savvy at all and I see how easily she's fooled into installing all sorts of garbage. The other day she was about to install and use a fake WhatsApp. The bottom line here is that you and I will keep installing the right software but many won't and will end up with compromised iPhones or at the very least full of garbage apps.
