How social media companies help authoritarian governments censor the internet Increasingly, the price of access to a global digital market is assisting the policing of online speech. The president of Nigeria, Muhammadu Buhari, was so outraged when Twitter deleted his post last Wednesday (2 June) that he ordered the country's mobile networks to block access to the social network and broadcasters to delete their accounts. While Buhari's comment – in which he appeared to threaten to return Nigeria to the appalling violence of its 1967 civil war – certainly looks like a violation of Twitter's policies, it's an unusual political intervention by the company (when Donald Trump threatened people protesting the murder of George Floyd with “shooting”, the post was merely flagged). More common are the requests governments make for the removal of posts that criticise them – and social media companies are often willing to comply.
