Wonder if they did it on purpose. I can't figure out what the purpose might be - a whistleblower wanting to raise awareness about it and realizing they didn't want to have to relocate to Russia or say live an Ecuadorian embassy for years. Or, I can imagine, a rogue agent wanting to warn someone they are on the list without communicating with them privately, so there is no metadata linking them, and they "accidentally" leaked the whole list.
