All the Arab league countries are removed, that's what it's based on.
I doubt these guys would have removed Djibouti otherwise, they know nothing about the country.
I have actually seen a version where Somalia stays on the map, but due to trolls, we have been removed.
Nobody knows Jabuuti, it appears only in memes. Thats why its on the map. Jabuuti is part of the Arab league too.
