I don't believe your assertion that upgrading Macs breaks the EULA. Can you explain this statement?

Does Apple really document how to break their EULA on their website: https://support.apple.com/en-us/HT205041

[drinchev]

Precisely. So how do you explain Hackintosh then? If I upgrade the CPU of a Mac Pro, I am obviously running OS X on a non-apple hardware.

Or the other way around. If I take the HDD of a MacBook Pro and put it on my Hackintosh, am I violating the EULA?

So I think the line is so thin and you can argue about anything on that topic.

I saw this from your link:

"Removing or installing memory

You should not manually upgrade or replace the memory in these Mac mini models. Instead, contact an Apple Authorized Service Provider or Apple Retail Store to install memory for you."

Yes. Upgrading the memory on some older Minis requires you basically disassembling the entire machine. I've done it. It's not brain surgery, but it's also not as easy as turning the little circle thing on other Minis. Nowhere does it say it violates any license agreements, just that Apple doesn't suggest you do it.
