Why not? But it really doesn't matter. He's dead. The real question is when will we stop asking this question?
It just doesn't matter in the long run. In fact, many photographers I know who shoot digitally for commercial work, are moving back to film for their personal work.
I shoot what I want as long as I can get the products that produce good photos. When, and if, the day comes when I can no longer get film, I will change. In the meantime the rest of the world can be a testbed for the darkside and I will skip over buying products that produce sub par images vis a vi film and have to be replace every two or three years because of new improvements or poor designs.
