From The Verge:
In April, Twitter opened its first office in Africa in Ghana, which some in Nigeria considered a snub. In its announcement, Twitter cited Ghana’s support of free speech, online freedom and the Open Internet as the reasons for its decision. Nigeria’s information minister said at the time that Twitter’s decision not to locate its Africa offices in Nigeria was due to misrepresentation of the country by the media.
Nothing like proving Twitter’s call as absolutely correct.
