The app is now asking to see your SMS messages, and the article discusses some of Facebooks recent privacy issues and how this change might be viewed skeptically. However, if you try to post a link to this article on Facebook it is flagged by their malware detection system. Other articles from FastCompany post without issue, so it looks like Facebook is explicitly blocking this article.
