China blocked Facebook following the deadly 2009 Ürümqi terrorist attacks because Facebook was negligently allowing ETIM-backed groups to spread disinformation and hatred via their platform. Facebook subsequently refused to filter such content and the ban continues to this day. Control over the Xinjiang/Uyghur narrative is paramount in the "New Cold War" declared against China by Pompeo this July, so Facebook's actions are not surprising.
