What if it's some junior given a job beyond their abilities, and struggling manfully using whatever tools they have to hand. Is it worth publicly trashing their name? What does their name really add to this article?

A good lesson. If you as an employer look at this history, and handle it in the interview appropriately (what did you learn / do better now for example) you can figure out if they did.

I'm sure lots won't, but if that is you as an employer you're worth nothing.
