It does in fact contain the word "man" though in a (normally) non-gendered idiom.

edit: just realised that there wasn't a space between "poor" and "man". However, it seems from a quick google search both versions (separate and a single word) are used for this expression.
That said, it only contains the word "boy" once in the entire article, and only in the provocative headline.
I think we can all look past the provocative headline.
