In which universe is polymorphism the opposite of isomorphism? Couldn't we just have said "JavaScript that runs everywhere" instead of trying to sound educated?

When you want to refer to the same concept over and over, it helps to give it a name.

Other examples: ajax, lamp, nosql, soa ... they may be buzzwords, but they are helpful. I don't see the problem here.

Isomorphism was already a word before Nodejitsu abused it. Your examples are acronyms and abbreviations.

Nevermind that this concept is not even worth a name.

It is common to repurpose words this way. I think it is called 'metaphor'. See also: half the names in technology and all nearly every apple product name.

Anyway, I find the term useful.

Metaphors make sense, that reusing of isomorphism doesn't, however you quote Greek words to justify your means.
