In the article is mentioned people that did not get that prompt and still have the contacts and calls uploaded, could this prompt been added later so people that used FB before it was added did not had the chance to opt out? I did not see in the screenshot an OS permission prompt, so if the app had the access locally a bug in the settings could have reset/flip the options and upload the data anyway, like how Windows forgets about your privacy settings on updates.
