Social media has had a very complicated role in Myanmar, where basically, the Internet is Facebook. That is pretty much the only Internet that most people know and use, and it has played a very complicated role. It is actively used by activists on the ground to promote democracy, to talk about protests, to raise awareness, to counter hate speech. It has played in many ways a very positive role, but it has also played a very negative one. There has been a huge amount of abusive speech on Facebook in Myanmar. It arguably helped fuel the ethnic cleansing and crimes against humanity that took place in Rakhine state.
As you say, the jury is very much out on the role that Facebook and social media play and whether it's positive or negative in Myanmar overall.
