He is more reckless than the author of the article. It does not benefit anyone that he revealed his identity, and it might affect him negatively.
Commendations should be made for his acknowledgement of the addiction, and making it public so others might realize too. I don't think identity has anything to do with this.

Actually, it might. From the original comment: "I won't post anonymously in case anyone wants to contact me" which means that if someone is struggling with a similar addiction, or wants to learn more about it, they can contact him and benefit from the additional information or context.
It might impact him negatively, but it might help others. That's what I mean by saying he's brave.
