Our working definition of a digital platform (with a hat tip to Harold Feld of Public Knowledge) is an online service that operates as a two-sided or multi-sided market with at least one side that is “open” to the mass market

Senators Markey, Blumenthal Push Zuckerberg to End "Friendly Fraud" on Facebook
Sens Ed Markey (D-MA) and Richard Blumenthal (D-CT) sent a letter to Facebook urging the company to institute policy changes in light of evidence that third party game developers manipulated children into spending their parents’ money. Previous reporting by the Center for Investigative Reporting demonstrated that Facebook personnel had direct knowledge that children were spending large sums of their parents’ money on in-app purchases without parental knowledge or permission. New evidence now reveals that Facebook has still not instituted key policy changes to address this issue.
Tech giants pressed in House hearing on policing extremist content
Facebook, Twitter, and Google defended their efforts to combat extremist content and misinformation online before the House Homeland Security Committee on June 26, but lawmakers walked away complaining that they aren’t satisfied with the tech giants’ efforts. “They’re going to have to do more,” said Chairman Bennie Thompson (D-MS), noting that he was dissatisfied with answers on a range of issues. Rep Max Rose (D-NY) offered some of the sharpest criticism, saying the tech firms are offering “technocratic” explanations while “people are being killed.”
President Trump signals US government ‘should be suing Google and Facebook’
President Donald Trump said the US government “should be suing Google and Facebook and all that,” then wagered that “perhaps we will,” in a new broadside against Silicon Valley at a moment when it already faces heightened antitrust scrutiny in Washington.
Artificial intelligence can't solve online extremism issue, experts tell House Counterterrorism Subcommittee
A group of experts warned the House Counterterrorism Subcommittee that artificial intelligence is not capable of sweeping up the full breadth of online extremist content — in particular posts from white supremacists. Lawmakers cast doubt on claims from top tech companies that artificial intelligence, or AI, will one day be able to detect and take down terrorist and extremist content without any human moderation.
Senators spar with Google exec over use of 'persuasive technology'
Lawmakers expressed disbelief when Maggie Stanphill, Google’s director of user experience, told the Senate Communications Subcommittee “No, we do not use persuasive technology at Google.” At issue before the panel was how algorithms used by companies like Google, Facebook and others might influence their users. Stanphill's statement prompted pushback from senators who had been scrutinizing the company over its content decisions on platforms like YouTube. “You don’t want to clarify that a little further?” Sen Brian Schatz (D-HI) asked.
The hearing will examine how algorithmic decision-making and machine learning on internet platforms might be influencing the public. Witnesses will provide insight on ways technology companies use algorithms and machine learning to influence outcomes, and whether algorithm transparency or algorithm explanation are appropriate policy responses.
Witnesses:

YouTube under federal investigation over allegations it violates children’s privacy
Apparently, the Federal Trade Commission is in the late stages of an investigation into YouTube for allegedly violating children’s privacy, in a probe that threatens the company with a potential fine and already has prompted the tech giant to reevaluate some of its business practices. The FTC launched its investigation after numerous complaints from consumer groups and privacy advocates.

Public Highly Critical of State of Political Discourse in the US
Large majorities say the tone and nature of political debate in the US has become more negative in recent years – as well as less respectful, less fact-based and less substantive. One takeaway: By a wide margin (66% to 32%), more people say social media companies have a responsibility to remove offensive content from their platforms than say they do not have this responsibility. But just 31% have a great deal or fair amount of confidence in these companies to determine what offensive content should be removed.
