> We seem to have gone from FB being the enabler and hero of 'arab spring' to now being accused of being a tool of darker forces against states.

Well, (1) you may have confused FB with Twitter in regard to the Arab Spring (both were involved, but Twitter seemed to get more credit at the time), (2) the Arab Spring itself was a set of anti-State uprisings, and (3) in Myanmar, the atrocities FB is accused of facilitating were committed by, rather than against, the State.
