Do you have a source on them intentionally stoking genocide? I’m not fan of Facebook, but if there’s reliable evidence on that I’d expect summons to The Hague in short order, which I’ve yet to see.
Some people certainly believe so[1], there are also plenty of other links if searching for ’facebook myanmar genocide’ (though I would assume they a few common sources). But intentions are of course hard to prove.
