> I answered saying that we already have a negative commandment, don't call people what they don't want to be called (like wrong pronouns), which is proper

Straight from the article. You can tell people not to call you something, Cellio will not call you that thing. However, they will not go out of their way to call you what you want to be called, it's their choice in what they call you, as well as how they respond to names you don't like.
