Officials point to Twitter’s treatment of posts from the separatist leader Nnamdi Kanu, head of the outlawed Indigenous People of Biafra (IPOB) group. Based in the U.K., Kanu uses Facebook, Twitter, and internet radio streaming to broadcast his separatist messages to Nigerians in the country’s Southeast region. The Nigerian government has complained that IPOB’s “hate messages” have been flagged consistently, but Twitter has said the tweets do not violate Twitter rules.

I think that promoting the separation of entire countries, specially those how are uncomfortable for western countries, are approve for these "social networks" (Think Tanks). The Nigerian government has a lot of contradictions, specially with the Muslim communities, but IPOB, included Boko Haram (With its active propaganda machine in Twitter/Facebook/Youtube of Africa) plan to create Modern Apartheid states worst than IsraHell. In this sense I agree with the Nigerian government to create a sovereign internet.
