Respectfully, I think you're missing the point. It's not about any one person being interesting enough. The fifth amendment gives the (American) people a right not to incriminate themselves. The point is that a sizable chunk of the population can now unlock a lot of information about themselves without the fifth being an issue. I don't think the writer of the article claims that this is an effect that was actively saught after by Apple or the govt - it's simply here and people need to know and think.
It's as if someone invented a key you could turn to remember whatever you forgot. Great invention, but the article is saying: be aware, turning the key is not self-incrimination, and so now you have no 5th amendment.
