William: tech companies still have a lot to learn

london - Tech companies like Twitter and Facebook still have a lot to learn about the power they have. Prince William said that in a speech he gave about a cyber-bullying task force, which he launched in 2016.

William pointed out that social media have positive sides. 'The friend we lost sight of is suddenly part of our life again, and the grandparents who live far away can now keep up to date with the daily life of the family they love so much.'
