I'm not sure exactly what the extent of the "facilitation" was in the first link, so what I'm about to say might be a little vague, but the second doesn't appear to be about them covering up their role in said "facilitation", but rather their refusal to provide so much user data to The Gambia looking to prosecute Myanmar officials for war crimes.

The way you've phrased that makes it sound as though Facebook were trying to hide the actions they took to facilitate things, which I think is a miscommunication.
