So can the number of hairs on a dog's tail.  That doesn't mean
that any of the three concepts are related.

Except for the name, and certain rather esoteric considerations
of what would happen in a perfect crystal at 0K (an unattainable
state, BTW), information entropy and thermodynamic entropy are
unrelated.  In particular, there is no equivalent of the laws of
thermo for information entropy; in particular, spontaneous changes
in the system can increase or decrease the amount of information.

Even from my brief glances at those threads, I don't see how that
can be.  Both information theory and thermo were discussed in some
detail, as well as the lack of any relation between the two types
of entropy.  Admittedly, the respondents weren't telling you what
you seemed to want to hear, but that's not their problem; they were
just explaining how the universe behaves, and any issues you have
with that are strictly your problem.
