Is it because we're medieval scribes and we really want to use the Latin faeces to indicate our scholarly intentions, instead of the Anglo-Saxon shit that everyone around us uses?
There is no reason I can think of that comports with a technological or innovative worldview.
Including cybersecurity. ("Shit" is just an identifier or a guessable string with 13 bits of "chaos" completely equivalent to "Dave" or "Phil.")
Edit: Well I see small-minded superstitious dunderheads have shown up to downvote me, so FUCK CUNT SHIT ASS
