Please explain any difference between the meanings of "the information
that one could extract if there were no Heisenbergian constraints" (what
you said) and "the information that exists in any given thing or system"
(quoted from the article).
Then, given that there is none, tell us why the "reviewer" (it wasn't
actually a review) was wrong to use that phrase, when physicists treat
the structure of matter as information in the context of the application
of communication theory to thermodynamics.
