I've no problem with how they used it in the article. At the moment, the overlap of 'professional photographers' and 'people skilled in metadata forgery' is pretty slim and (IMO) the data is unlikely to have been altered in this case. My point is, in the future, you won't be able to even use the metadata as a starting point because all of it could have been changed with easily-available and well-known tools.
