If the title is confusing, the least someone could do before taking the time to write a comment with a basic question is to read the article. The point of the title is not always "to summarize the article".
It might be that the title may be clickbait-y, but that is I guess to be expected in this day. Someone reading has the choice to just not interact if that title is too much bait.
Here it's a loose game of word association. For example, title says "GNU" in any context so we get 300 comments with unrelated anecdotes about Stallman. The comments section becomes stories about whatever random nonsense is in the top 2-3 comments. When it was being published, n-gate[0] was great at highlighting this.
