Why would apple be fine with this? They validate all the hardware that goes into their boxes, work with companies to offer decent drivers and support for various features and so forth.
Saying apple should let other companies build cheap little clones and sell them is akin to saying Ford should just start putting Ferrari badges on the Focus cause really, they are the same hardware..just cheaper version. Never mind the effort that goes into designing, building, marketing, and selling a Ferrari, just let Ford call the Focus a Ferrari and profit from someone else's success in a niche market. Hel why stop there, Kia can make an even cheaper Ferrari! We can all have One! Never mind that it just wouldn't be the same, or as good.
Apple sells premium hardware, full stop. They don't want to offer anything under $1,000 and that's their business model. Maybe things will change later, but for now apple sells what they sell. And premium doesn't always mean absolute peak performance, the software, design, aesthetics, and so forth are all part of the equation.
