Not too hard to find exceptions. IMO it's a pretty worthless law even if only stated for entertainment value. A lot of times a yes-no question, like above, is just used as a low-effort intro to a low-effort article but sometimes a yes-no question could act as a well-thought-out intro to a well-thought-out article. It doesn't take too much experience to understand when a title is just being vague to draw you into a bad article.
