It can't. Information is not a particular thing whose attributes
cannot conflict with one another -- "information", on the other hand,
is a word that can be, and is, used in various ways, some of which are
quite different from each other. Communication theory, as that term is
normally, consensually used, is about the fundamentals of communication:
what's required *before* meaning can be conveyed.

Nobody is messing with your concept of information, Joe! But you should
face up to the fact that there are other ways in which that word is used.
Equivocation is unfortunate, but it's also a fact of life.
