First of all, Apple is making more money from Macs than iPads. In the last quarter, they had ~$6B in revenue from Macs versus $4.2B from iPads (~$7B same quarter last year). Are you seriously suggesting that Apple should drop that kind of money just because the iPhone had ~$30B instead? (Source: http://images.apple.com/pr/pdf/q4fy16datasum.pdf http://images.apple.com/pr/pdf/q4fy16datasum.pdf) They're not going to make macOS a paid OS for sale on other hardware, which means they'd lose $4-6B per quarter, that's $20b revenue a year they can use to improve all products. They're not going to keep making that much money from iPhone forever, it will decline eventually as competitors keep getting better and better. Google is entering the market with products that finally rivals iPhones and Microsoft/HP/Dell with Surface/Spectre/XPS products that does rival Macbooks. This is Apple, they want total control of the entire stack and the only way to do this is to do it themselves. macOS will not survive on other hardware with questionable QA. I started hating W10 simply because of its driver issues, automatic brightness stuff that I can't turn off on SP4. Same Win10 on my Macs, it works much better and consistent. There's no way Apple will do this to macOS.
