>Real question: Is there some social etiquette rule that says describing to a news audience as "unknown" is rude? Honestly, I've never heard of that. You and the other person calling it a compliment are either the same person, or you're both social robots who think referring to human beings as Unknowns is a nice way to treat a person. Just use his name in the headline, how hard is that?!
Because "unknown" in the title is more descriptive of the general public's (lack of) awareness of the person's identity. (I assume Bloomberg's audience is mostly North America.)
It's very common to use "unknown" in the title and the full name in the body of the the article which Bloomberg has done here. The article's first sentence has his full name: Zhang Yiming. To me, this appears respectful and not insulting.

I think throwing a veiled insult at me is ironic.
