I agree and think Apple promoting and implementing it in their products is wonderful. But most of the world can't afford Apple products and therefore are effectively denied this human right.
It would be great if Apple could provide a low-cost line, probably under a different brand name, that implemented the privacy technologies in otherwise basic phones, laptops, etc. Or maybe license the privacy tech to someone else who does that. (I realize it might be much more complicated than what I describe; for example, the security tech could be too tightly integrated with the rest of the product. Would they have to license iOS? A stripped down version?)
I'm not complaining; it's not Apple's job to solve this problem created by other phone and OS makers. But they could make a big impact and I don't think it would take sales from Apple products; an otherwise cheap phone with Apple's boot security subsystem isn't going to compete with an iPhone.
