It is quite another thing to not understand, deny to one's own consciousness an appreciation of the extent to which they do not understand, and further denounce the the substance and the purpose of the deeper understanding of others as being in some way either impractical or irrelevant to the subject(s) at hand.

It took me several attempts to understand the topic sentence of the above paragraph.  You might find the FOG INDEX interesting and this SELF EVALUATIONmight be instructive. 

You might think that someone who puts a lot of energy into insisting, under the banner of clear communication, on the use of preferred definitions of some words would put more energy into communicating clearly.

I know that he has written about it many times here.  Please send a link to his "article".  Many thanks.

If one is using terms that are ambiguous or frequently misunderstood, I believe the better course is to define those terms.

LOL!   I was trying to be a bit subtle.

AHA!  The nickel drops ...  JJ = GB ??  Good write-up.

I agree that defining is safer.  But commonly accepted terms like f/??!!!.  or even Exposure??!!

Their definitions have been inscribed in both the photographic and general optics literature for a century.  For authors to re-define (to sell books) or to prove a fanboy point is plainly opportunistic or sloppy.

The question is WHICH ONE IS THIS ?  Charles Lutwidge Dodgson ??
