I get the joke, but the sources aren't self-published. They're published by an instance other than the author and that's good enough, that's what the self‐publishing rule is about.

The COI can hardly apply to members of a fairly broad group writing about the group. By that logic, Americans shouldn't write about the USA, only gay people could write about heterosexuality, etc.

Conflict of interest (COI) editing involves contributing to Wikipedia articles about yourself, family, friends, clients, employers, or your financial and other relationships.

I swear I'm not this insufferably unfunny most of the time.
