This is an interesting article, that for once has prompted a couple of reactions.
1) I agree it is a matter of taste, but IMHO I have problem with the concept of being a Fine Art photographer. Collins Dictionary contains the following meaning of Fine Art in American English:
'a visual art considered to have been created primarily for aesthetic purposes and judged for its beauty and meaningfulness, specifically, painting, sculpture, drawing, watercolor, graphics, and architecture'
This seems to indicate that the word 'judged' means others decide whether it is fine art, not the artist/photographer who created the image.
2) Putting a human in the image can be useful for scale and context. Architecture is usually in the context of human use. A photograph I took in 2012 in the City of Arts and Science in Valencia is a case in point. Those to whom I have shown it all agree that the figure much enhances the image. The English photographer, Charlie Waite, in one of his books, shows an image of a landscape with a small figure in red in it. Block that figure out and the image loses much.
As I wrote it is a matter of taste; YMMV.
