PolygamousRanchKid shares a report from TechCrunch: So much for "We are accountable"; Facebook founder and CEO Mark Zuckerberg has declined a summons from a UK parliamentary committee that's investigating how social media data is being used, and -- as recent revelations suggest misused -- for political ad targeting. The DCMS committee wrote to Zuckerberg on March 20 -- following newspaper reports based on interviews with a former employee of UK political consultancy, Cambridge Analytica, who revealed the company obtained Facebook data on 50 million users -- calling for him to give oral evidence. Facebook's policy staff, Simon Milner, previously told the committee the consultancy did not have Facebook data. In a statement a Facebook spokesperson said it will be offering its CTO or chief product officer to answer questions. Today, CNN reports that Mark Zuckerberg has decided to testify before Congress within a matter of weeks, and Facebook is currently planning the strategy for his testimony. "The Facebook sources believe Zuckerberg's willingness to testify will also put pressure on Google CEO Sundar Pichai and Twitter CEO Jack Dorsey to do the same," reports CNN. "Senate Judiciary Chairman Chuck Grassley has officially invited all three CEOs to a hearing on data privacy on April 10. That means Washington, not London, will be the stage for the trial of big tech."
