It worked on me (It was a leading reason for going back to an iPhone after switching to android. The others being customer service and iMessage). And I think it will be an increasingly powerful differentiator as time goes on. They don't need to do the reeducation.

I think the answers there are pretty obvious, and owning the "we care about our users, their privacy and security" frame is going to be an increasingly powerful one.
