Etiquette question about fandom ex-friends who become TERFs

TL;DR: so there’s this HP fandom person, MelusinaHP, who I was friends with for years. She’s a militant TERF now. I wrote her birthday fic or fic to her prompts way back in the day. Should I delete her name off the Author’s Notes on AO3 given how comprehensively over our friendship is, and given she might still be a bit of a presence in HP fandom?
