This leaked audio from Facebook — where Mark Zuckerberg promises that “you go to the mat and you fight” Elizabeth Warren — is a reminder: any corporation that has power over the speech of billions of people is still a corporation with its own interests. And those interests don’t match yours or mine or the interests of democracy.

You don’t have to support, or even like, Elizabeth Warren to understand that.

Do you trust Facebook not to tip the scales in favor of Zuckerberg’s interests? I sure don’t.

This is about Facebook and a specific presidential candidate — and it’s also about giant corporate communications platforms and how they subvert civilization.

PS Reminder: Instagram is Facebook too.
