Elon Musk has bought Twitter for a staggering $US44 billion, in a move that will shift control of the social media platform to the world’s richest man.


Musk says his priority will be the promotion of free speech, which is being interpreted by some as signalling his intention to remove some of the curbs on hate speech and misinformation.
