Has free speech been cancelled? | UpFront

Debates around free speech and “cancel culture” seem never-ending in democracies around the world. Central to the conversation are technology companies like Twitter and Facebook, which in the United States have played a role in recent months by denying former President Donald Trump and many of his supporters a platform for spreading disinformation. But could this be a slippery slope?  And who gets to decide what the limits are on free speech, if any? In this UpFront special, Marc Lamont Hill discusses it all with journalist and author Glenn Greenwald and columnist and professor of journalism at Middlesex University Yasmin Alibhai-Brown.
