Andy Mangels was not a DC staffer at the time (or ever), although he may have been on the staff of Amazing Heroes at the time (he was certainly one of their most frequent writers). He would later become an occasional freelance writer at DC. So his name doesn't help make this semi-official.

And from the way Mangels mentions Roy Thomas and Steve Englehart I assume he just went to them with a few hard questions (the way we at the database sometime will ask creators questions on Twitter). I doubt they approved (or even read) the whole article before publication.

So I don't think this is even a little bit official.
