Ask HN: Is StackOverflow being ruined by its mods?

See http://i.imgur.com/cGtm5.png. I'm not the question's author; I recently searched for this question, specifically pros/cons. Seems nowadays that about 5% of the questions on SO I look up and are perfectly legitimate to me are found to be locked, with a warning to others to knock it off. This is up from ~0% when I started using the site. Every forum I've loved eventually gets lock-happy mods. What does HN think? Am I the unreasonable one? I don't see how this question is unworthy according to the FAQ that SO refers to.
