I think you need to review the definition of the word "most", and then read the section on what is on-topic, as well. When you do, you'll realize that there is no black and white objective line, and that's by design.
You are wrong, because this comes up ALL THE TIME, and the simple answer is that it's not off-topic if enough HN members find it interesting enough to upvote.
I could be wrong, but I don't see how.
