Apple segment their product range just like any sensible company. There's a range of products that increase in power, and in profit margin. People who can afford to buy the highest end products end up paying over the odds, because they're usually the least sensitive to price.
This doesn't mean that Apple is about user experience. Frankly, that's hogwash. They're about corporate profit, in the medium term. And if people end up buying lower end devices and upgrading it themselves, I can easily see them seeing this as a lost profit opportunity, and doing something like whitelisting. It's little different than Intel eventually getting around to locking down frequency multipliers, and selling unlocked chips at a premium.
