Unclear to me from the comments why that submission was flagged. It seems reasonably on topic to me and not intrinsically flamebait-y. I guess enough people just hit the flag button.
That's fair. This submission title was editorialized a bit too at the time of my comment but I guess it survived not being flagged long enough for someone (yourself maybe) to adjust the title.
