We're in a technical forum, discussing a term of art that refers to a very specific bad practice.

Lucketone's argument is essentially saying that the bad practice itself isn't actually a bad practice by equivocating the term of art and the plain language definition.

The problem is that the term of art is confusing to technical people. See TFA. Technical people make logical leaps from "avoid security through obscurity [in the specific context of security systems which depend on obscurity and for which there are better alternatives than obscurity]" to "you should never obfuscate JavaScript" because the word is imprecise.
