While they are deleting the imported contacts, that doesn’t undo any potential shadow profiles they generated, any training to their ML models that associate users (relationships), or any training to their advertising models. I believe Facebook doesn’t care about the contacts themselves. They wanted all of these collarary benefits that the general public will not be thinking about.
