Facebook founder and CEO Mark Zuckerberg testified to the Joint Senate Judiciary and Commerce hearing with Mark Zuckerberg in Washington DC on Tuesday, regarding the company's major data breach that came to surface in March. «He didn't do enough to prevent these tools from being used for harm as well. And that goes for fake news, for foreign interference in elections, and hate speech, as well as... Еще developers and data privacy,: said Zuckerberg. Under questioning from Senate committee members, Zuckerberg apologised for his 'mistake'. «I'm sorry. I started Facebook, I run it, and I'm responsible for what happens here.» «It will take some time to work through all the changes we need to make across the company, but I'm committed to getting this right. This includes the basic responsibility of protecting people's information, which we failed to do with Cambridge Analytica,» he added. Data mining company Cambridge Analytica developed a system analysing personal information from Facebook users in America to target them with personalised political advertisements in the hope of influencing voting intentions. Although the allegations of data breach were denied by Facebook, the scandal has caused a sharp decline in the share price at the world's largest social network.
