Nothing in here is exactly wrong, but we do have to acknowledge that this whole back and forth has essentially informed everyone that:

Facebook considers the keys to their kingdom to be worth $2,500. OR Facebook doesn't know what the keys to it's kingdom look like.

Facebook will not update keys/credentials even if they are known to be compromised.

If you have the keys to the kingdom, you can use them and Facebook won't find out about it unless you tell them.
