How do complain about a post closed for the wrong reason

Best way to stress test a website

I was looking for ways to stress test a website, and saw the question was closed as a duplicate. However the article said it was a duplicate of a question only for Microsoft specific websites. Apparently the person closing the article thinks the internet is a subset of microsoft technologies (bet microsoft would love that).

I hope that stack overflow allows questions like these (that do not ask for opinions). Clearly the person closing the article was biased towards microsoft.
