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.
