The op is probably not the world's most reliable narrator. Based on his very, very specific preferences around writing I'm guessing he can be a bit prickly when it comes to feedback. The manager might have had a bad day and dreaded having the conversation and ended up with this. Still very stupid, but OP is not quite so clearly the martyred hero in this version.

Agreed. Anyone who believes they can write an English sentence that is clear, exact, and bulletproof is foolish at best.

This is the reason professional jargon exists: to narrowly define certain words. But even then, only a tiny fraction of words are so restricted.
