I think the reaction is stronger when borrowing the foreign bits just feel like "cheating". If they were borrowing words with meanings that are specific to that language are hard to convey in other languages it would make more sense. Here the new word is basically "me-leftover"; it feels exactly the same in Japanese than when spelled out in English, so either the author could accept the cheesiness in English and run with it, or choose a better fitting word in a different language that actually brings nuance to the thought. Just borrowing another word to make it look mystical isn't wrong or forbidden, it just feels lazy and a waste of good words. Also we're in a connected world, and there's enough people speaking multiple language that "exotic" words have a way lower chance to be actually exotic anymore.
