Facebook is under fire for allowing Russian propagandists to buy ads during the 2016 election. This week, how we do and don't hold tech giants accountable.

1. Max Seddon [@maxseddon], Moscow correspondent for The Financial Times, on the push by the US government to register RT and Sputnik under the Foreign Agents Relations Act and why the effort to "do something" about Russian propaganda is misguided.

2. Julia Angwin [@juliaangwin], investigative journalist for ProPublica, on their new crowdsourcing project that aims to monitor otherwise inscrutable Facebook political advertisements.

3. Matt Stoller [@matthewstoller], Fellow at the Open Markets Institute, on understanding Silicon Valley's behavior through the lens of monopoly and why he believes Americans can, and must, demand more.

4. Utsav Sanduja [@u], Chief Operating Officer of the alt-right-favored social media network Gab, on their antitrust lawsuit against Google and why they see a need for a pro-free speech social media platform.

5. Paul Ford [@ftrain], tech author and commentator, on the difficult ethical questions that surround massive tech platforms.
