There's nothing to defend here. The reason there's a free form field for the title is precisely allow people to write titles for their submissions. Meanwhile, content of the article can be fine even when there's a clickbaity headline, or sometimes it's useful to link an article as an illustration or a commentary without endorsing it.

The only way people would get confused is if they didn’t bother actually looking at the article, at which point they don't have anything meaningful to contribute to the discussion. So, not really sure what problem you're trying to solve to be honest.
