I really don't see why Facebook is blamed for this. That ethnic tension was present way before Facebook even existed. It was kept in check by an authoritarian military dictatorship and then bubbled up in the transition to more democracy, which really shouldn't have been unexpected. Facebook was just there at the wrong time, and happened to be the way people were communicating at that time; Aung San Suu Kyi has also gotten a lot of criticism for being in this even though she has been mostly powerless to do anything about it either.<p>All Facebook can do is stop the propagation on their network. Even with China-level censorship, they would probably need serious manual effort or even a complete network shutdown to stop being a medium. But the same problems will still occur using other channels, maybe the hate won't move as fast, but it will still be fast enough to cause plenty of damage.
