Look man, i get that you're probably a diehard Apple fanboy, but you're really missing the point.

Fact 1 - Microsoft openly supported a multi-button mouse and offered it to you. PCs that were budled with Microsoft windows came with a 2 button mouse. They trusted their users to understand how it worked.

Fact 2 - Apple supported mutli-button mice but refused to bundle it with their computers until 2005 because they didn't trust that users were smart enough to use it.

These 2 facts lead back to the original point. That PC makers trusted their users were smart enough, and Apple didn't. That Apple only relented when they were proven wrong that people could very easily use and understand a multi-button mouse. That they were late to the party to bundle it with their computers.

Prove me wrong on either if the 2 facts.

And the "walled garden" is an ethos which has dictated all of Apples choices. They want to have full control over what us done on their hardware and software. It has merit to our conversation.

And honestly, your arguments will never change the fact that Apple's approach to hardware and software has been a deterrent to user for decades.
