Does that concern ( https://medium.com/@cellio/dear-stack-overflow-we-need-to-ta... ) have anything to do with the pronoun code of conduct problem at issue here, or is it totally unrelated other than Cellio's involvement?
I have to admit, having read Cellio's summary of the situation, I'm puzzled why "avoid using pronouns to refer to people where possible" would be a controversial view. If you use the wrong one, it may cause harm. If you use none at all, your interaction is more futureproof. For example, if I write about a person who feels comfortable being called "him" but the person later chooses to prefer being called "her", but if if I had avoided using "him" entirely in the first place, then I would never worry about having to retroactively edit or delete my writing to avoid harm.
