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.
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.
