> My understanding is that since the Cambridge Analytical issue, Facebook now manages all its data access in-house That was the case since, at least, I joined FB via an ad-tech acquisition, mid 2010s. We had a feature that allowed customers to host their own assets. That was the first thing that we had to remove after integrating with the FB stack. /edit: the CA scandal was ~ mid 2010s, my statement doesn't help. We joined before the scandal, by quite some time.
