Frances Haugen, the former employee who accused Facebook of putting profit over safety, has testified before the US Senate. The whistleblower condemned the extreme secrecy and lack of transparency around Facebook and how its algorithms work. 'I’m here today because I believe Facebook’s products harm children, stoke division and weaken our democracy,' she said. 'The company’s leadership knows how to make Facebook and Instagram safer, but won’t make the necessary changes because they have put their astronomical profits before people.'
