The benefits of the Christchurch Call are being debated in the wake of allegations that it's silencing member organisations.  Jacinda Ardern established the global alliance in 2019 to combat online extremism in the wake of the Christchurch mosque attacks.  But Newstalk ZB has revealed a member organisation of the Advisory Network has quit, claiming it was pressured not to release a report suggesting India isn't honouring its commitments.  Tech commentator Peter Griffin told Mike Hosking that the alliance has helped achieve some global change, but it's ultimately a voluntary collective.  Griffin says big-tech companies have little incentive to act and would rather spend the money on advertising.  LISTEN ABOVE    See omnystudio.com/listener for privacy information.
