FB audited a bunch of metrics and found issues with 4 out of 220. The narrative being pushed here is that all of them nefariously favored FB. The only problem with that is that it's not true.> """Elsewhere, Facebook admitted to exaggerating the number of full views that video ads received"""You can tell they didn't do any homework, since the issue was that full views were under reported when the audio and video tracks were not the exact same length.
