I'm not going to express an opinion about the photo other than general surprise about how varied a concept of 'faked' appears across all commentators.
What really interested me was the article's description of Photoshop's XMP metadata block, giving a history of saves/exports/edits. I never knew this level of detail was stored with the images. It also makes me think, how long until there are tools to easily edit such metadata? The website takes the metadata as gospel truth. At some point in the future, this is not going to be a reliable position to take.
