Exactly the point that jumped out to me as well. A random guy taking my idea and pitching it to others without my consent. It's not about whether it'll work out or not, it's about getting permission to do what the guy did.

If the Biz guy had said "Hey, let me run your idea through some people I know and see if they're interested. Sounds good?" Then it'd be totally fine. (Maybe that's what happened but over looked in the article?)
