Apple is what it is because they tightly control the end-to-end user experience, from the hardware to the software. You can't maintain that and open up the hardware ecosystem; it's an either/or choice. So far, their choice has worked out really, really well for them, so why should they mess with that?

I'm sure you're aware of Apple's fairly disastrous entry into the world of Mac clones back in the day. What you're arguing now is essentially the same theory back then: clones would benefit them by increasing the marketshare for their OS. Instead, clones just cannibalized Apple's own sales and diluted their brand with a bunch of crappy knock-offs. I'm not sure why anyone would expect it to play out differently now.

Sure, it might be in your interest as a consumer to have choice in hardware, but I don't see how it's in Apple's interest to do so. They seem to be doing pretty well precisely because of the choices they've made to lock things down, not in spite of them.

That's not what OP is saying:

If the Apple hardware ecosystem were open like that of Windows you'd have major companies all over the world evolving the platform in wonderful ways. Performance would go up and prices would come down.

This isn't "moar market share," it's "the end user would benefit greatly if Apple hardware opened up."

Today is much different than the Mac clone era for two reasons:

(1) Apple clearly has no intention of offering a high-end desktop solution. Instead of losing those users to high-end Windows or Linux machines, they could keep them in the ecosystem by licensing OS X for use in boutique-style desktops.

(2) Apple holds much more power now. In the 1990s they licensed Mac OS from a point of weakness; today they could license to high-end, boutique manufacturers who meet their design standards.

Is this the right way forward? Maybe, maybe not. But OP's suggestion does not necessarily lead to the Mac clone days of the 90s.

That isn't what has happened with Windows machines, though, or Windows itself. It's also the opposite of what has happened with Android: you've ended up with a fractured market full of underpowered phones running obsolete and incompatible versions of the OS.

All this Adam Smith idealism is great until we look at the real world, where the barriers to entry, integration costs, barriers to accurate consumer knowledge and platform compatibility hurdles are too high for competition to actually produce ideal outcomes.

If people wanted a competitive platform with a propitiatory OS they'd all be developing on Windows. There is no reason for Apple to try to compete in the same space, especially not when they are winning everywhere that matters for consumer electronics.
