Fair enough...I saw his name at the top and immediately knew who he was but only because I work in media. However, Carney would be right to assume that his main audience -- the media -- will also recognize his role.
That said, I don't know if this is them trying to be intentionally deceptive or if this is just a clunky use of the medium (no pun intended). It is his first post on Medium, and it's written not in the first-person (as a way to make a personal connection with the reader) but uses "we", e.g. "We were in regular communication with Ms. Kantor from February through the publication date in mid-August"...I don't think there's much evidence to show that they are trying to hide the author's bias or position, other than it's on Medium and not on news.amazon.com.
