In “Careless People”, in the chapter on the Rohingya Genocide, a case is made for Facebook’s complicity in it. Essentially threatening and violence-inciting content got past moderation because the font that was used didn’t support Myanmar text. So there would be a report on a post but all the mod team would see was missing Unicode characters and mark the post as okay. By the time the serious violence started it was too late.
Now, I am not claiming a lack of text support caused a genocide, and I don’t think Wynn-Williams is either. Facebook was certainly culpable though, the military had direct controls over what was allowed to be posted and suppressed dissent. The issue could have been caught much earlier on and perhaps mitigated had off-shore moderation teams been able to read posts that were being flagged.
This is from 2016, it's a fairly detailed study of what happens when a rural, barely (or illiterate) population gets access to a powerful social media tool:

I heard it was because .. in a country where they did tie-ups with mobile operators to 0 rate face book traffic, to make it to the point where the internet and facebook were the same thing to many people, they also only employed a handful of moderators. Meanwhile Politicians were posting incitements to violence on the platform.
If you read contemporary reporting about anti-Muslim riots in Myanmar https://www.reuters.com/article/world/special-report-buddhis... you may learn that there were Buddhist monks traveling the country, giving sermons to crowds of thousands of people, telling them to treat Muslims as enemies, and stickers being used to visibly signal alignment with the movement.
Careless People is a story about Facebook from inside Facebook, so of course it adopts the viewpoint that Facebook's moderation decisions are very important, but ultimately they were a sideshow to what was playing out on the ground. This goes double for military attacks on Rohingya villages, which can hardly be explained as spontaneous reactions to some Facebook post.
In any case, Facebook moderators literate in Burmese would've known to use the right font, whereas for Facebook moderators trying to deal with a language they can't even read, the font choice would be the least of their problems.
