The problem with Apple's approach is that EVERYONE has the same right to privacy. However, by selling very expensive hardware, Apple heavily limits who can have privacy. In other words, privacy is now a luxury item rather than a right. But what else could we expect? in the capitalist world even staying alive is a luxury.
Yes, it all comes down to money. I wouldn't consider Apple pricing "luxury," but it's certainly higher. That higher price brings a variety of potential benefits/advantages, of which privacy is one.
The same can be said for the price of a well-made lock for your door, or police protection for your neighborhood. These things come at a cost, even when the cost is hidden. If those with no money get these benefits at no/low cost (which arguably they should), then the money had to come from somewhere else, whether it turns out to be exploitation of natural resources (oil lease revenues), higher taxes on the middle class and wealthy, etc.
The US has a particular antipathy these days to government-run redistribution of income (redistribution of wealth via commerce is another matter). We're in one of those periods of extreme that will eventually force a swing in the other direction... and so the pendulum goes.
