"Should I leave America if I don't like the NSA?"

Yes. That would probably be the easiest thing. It's not like the NSA are going anywhere anytime soon. Maybe move out of the Area 51 tin-foil campgrounds worrying about who knows when you're in the bathroom. Nobody is forcing you to buy Apple products or any other smartphone for that matter. The world managed just fine before them, and if it makes you happier, I'm sure you'll manage just fine without one too.
