As has been noted repeatedly, he didn't use film, so he clearly wasn't trying to promote the idea that film is authentic because it is faulty. Neither did he make the claim that prints made from paper negatives were the norm 100 years ago.
As reported, the article says (emphasis mine)
But shooting the large-format film was a relaxing and, most important, creatively rejuvenating experience. With no motor drive to capture three frames every second (as with my Canon 5d Mark II cameras), I was forced to slow down and think about each frame.
Regarding the "unpredictability" of the Lomography experience, you know what I mean, which is that bad technique is perceived as interesting. The fact that this bad technique is looked for, and is unpredictable because there is some random factor spoiling the final result, does not change my perception of the Lomography aesthetic as being based on the problem rather than on the solution so to speak.
In the end it's all personal tastes. One can bake bread in a defective wood oven randomly leaking hot air and having a final result unpredictably half-baked and half-burned, and if he likes that bread so be it.
The problem arises when this kind of final result is somehow exalted - not in explicit words but as a general attitude or rhetoric - as the real authentic wood-cooked bread as opposed to the impersonal and too-perfect electricity-cooked bread.
Our point is that you can use a wood oven to make a better bread, not just a randomly defective one. The Lomography movement, while helping the sale of analogue material, risks to
involuntarily spread an equation of "analogue = randomly defective" which in the long run might damage analogue photography.
Said in other words, it seems to imply that analogue lost the "race for quality", and that people would use digital for quality and analogue for poetic/dreamy/unpredictable/old-fashioned/rejuvenating/whatever results.
The photographer whose work originated this thread, which IMO just applied this Lomography aesthetic to LF, seems to be spreading this message.
The OP criticized the perception of his work as being
"authentic" because "defective" and in this sense he used the words trickery and fake.
Unpredictable results can also be achieved by having your cat walk on your keyboard while using Lightroom...
