Why? Obviously, given the very basic nature of the question, this person hasn't looked into it at all.
Do you think I should have summarized all of the search results instead of just linking them?
What in fact is so meaningless about responding in this way?
Do you really think the question posed was so insightful and hitherto unanswered that we should all spend time considering it deeply here in this thread?
Honestly I find it extremely insulting that, in every thread about Windows, there are twelve or so people here who come here simply to wonder out loud why nobody uses their favorite non-Windows operating system or to extol it's supremacy (and how could anybody else possibly ever think otherwise??). That's crap.
