Well, I liked the paper, but I'm not knowledgeable enough to judge its true merits. It deals heavily with Bayesian-related questions, somewhat in Jayne's style, so I thought it could be relevant to this forum.
At least one of the authors is a well-known theoretical physicist with an awe-inspiring Hirsch factor, so presumably the paper would not be trivially worthless. I think it merits a more careful read.
Someone can build a career on successfully and ingeniously applying QM, and still have personal views about why QM works, that are wrong or naive.
Rather than just be annoyed with the paper, I want to identify its governing ideas. Basically, this is a research program which aims to show that quantum mechanics doesn't imply anything strikingly new or strange about reality. The core claim is that quantum mechanics is the natural formalism for describing any phenomenon which exhibits uncertainty but which is still robustly reproducible.
In slightly more detai...

Abstract
It is shown that the basic equations of quantum theory can be obtained from a straightforward application of logical inference to experiments for which there is uncertainty about individual events and for which the frequencies of the observed events are robust with respect to small changes in the conditions under which the experiments are carried out.
