I interpreted that differently as there’s a separate point about respecting people’s gender identity and purposely misusing pronouns would conflict with the guidance.

I read this to mean that there are ways to use they or per your address people when pronouns are uncertain. In that it I don’t know a pronoun then a good way to handle this is to use singular they.

I do this when gender is uncertain, as typical with the Internet and mailing lists and projects and what not.

I did not read this as allowing rude and inappropriate behavior to bypass people’s preferred pronouns.
