Despite the UK's request that Mark Zuckerberg testify before a Parliamentary committee. UK authorities say that if he wouldn't they would force him to appear before the committee the next time he enters the country. According to Facebook's head of public policy, Rebecca Stimson, Zuckerberg “has no plans to meet with the committee or travel to the UK at the present time.” To demonstrate the cavalier attitude Facebook has adopted, this letter was sent three days after the deadline Facebook was given to respond.
Rather than meeting with the UK's Digital, Culture, Media and Sports Committee as asked, Facebook had Mike Schroepfer, their chief technical officer, speak to them in lieu of Zuckerberg. Zuckerberg has already spoken before US Congress as well as agreeing to speak with EU legislators as they have requested.
Committee chairman Damian Collins has stated he is "disappointed" with Facebook's refusal. They are planning to issue a formal summons as a result that would compel Zuckerberg to speak with the committee if he enters the UK. Collins is attempting to make things easier for Zuckerberg and will even allow Zuckerberg to testify through a video call.
If Zuckerberg attempts to continue to shirk this request, the next time he is rerouted through England on a connecting flight he may find himself under arrest.
Facebook's official position is that requesting to see Zuckerberg is unreasonable.
As per Stimson's letter: “Facebook has now held lengthy meetings or evidence sessions around the world. … We are disappointed after providing a very significant amount of information … that the committee declared our response insufficient.”
Stimson also shared some information in her letter that included answers to questions that Schroepfer didn't answer when he testified on Zuckerberg's behalf last month. For instance, it was revealed that the presence of a Facebook like button on a website sends data back to Facebook when it is visited by a user whether or not the button itself is clicked. Such a like button appears on pages from 8.4 million websites. Facebook's tracking pixel, another way for FB to keep tabs on what the internet is doing in their other tabs outside of Facebook's domain appears on 2.2 million websites.
One reason to keep Zuckerberg away from the hot seat in the UK is the fact that the UK's Digital, Culture, Media and Sports Committee are offering much harder questions. There's also the fact that the Cambridge Analytica scandal originated from the UK. The committee hopes to continue to grill Facebook in order to “address significant gaps” in answers Zuckerberg and others speaking on Facebook's behalf in regards to privacy practices, the 2016 election, propaganda and more.
