Seems like it's trying to connect to Facebook's regular presence servers at their edge POPs.
Not pleasant, but so far we aren't sure they are transmitting any information of note.
In other words, this is no worse than, say, Facebook Messenger's permissions or behaviors, at least from what we know at this point. Worth further study.
