While the current title isn't bad, I think it's better to discourage the editorialization of titles, whether by adding tags such as "fiction" or by using catchy excerpts.
Having said that, the title in this case was changed to emphasize something which only made up a small part of the story: that the fictitious daughter was first sued in the womb. This is only briefly mentioned in the story itself, so the title editing looks a little bit like link-baiting to me, which is why I would have preferred if it were left unedited.
Of course, another HN poster pointed out that the author posted the title on twitter. Since I do not know or follow the author, I did not know that when I wrote my first comment, at which point it looked like the title was changed purely for the purpose of catching peoples attention. Had I known this 9 hours ago, I probably wouldn't have commented.
