A better headline would be "Facebook wants to inform users about the fact that scraping publicly available information is easy (and there's nothing wrong about that.)" Of course, that wouldn't get Vice as many clicks.

Don't publish information you don't want to be part of some database publicly on the internet. I wish schools had some sort of tech literacy class where they explained this stuff to people…

The information that was scraped here, though, are phone numbers that Facebook requires you to add to your account and that they promised would not be used for anything other than authentication purposes. Most of these numbers should not have been publicly available in the first place.

Which are "these" numbers? I thought that in fact, the numbers that were leaked in this batch were set public by the users at some point, and the ones which were not, were not leaked.

https://haveibeenpwned.com/ indicates my phone has not been leaked, nor my @facebook address.

No, it’s the people you may know feature leaking phone numbers. Facebook eats your contact list and matches it with users based on their phone numbers. This allowed you to see any random phone numbers profile. Facebook assumed that since you have the number you must know the person.
