I had never heard of this either:

> During the final months of World War II, codenamed Cherry Blossoms at Night, the plan of Unit 731 was to use kamikaze pilots to infest San Diego, California, with the plague. The plan was scheduled to launch on 22 September 1945, but Japan surrendered five weeks earlier.

> Our role is not to be bound by the First Amendment, but our role is to serve a healthy public conversation and our moves are reflective of things that we believe lead to a healthier public conversation. The kinds of things that we do about this is, focus less on thinking about free speech, but thinking about how the times have changed. One of the changes today that we see is speech is easy on the internet. Most people can speak. Where our role is particularly emphasized is who can be heard. The scarce commodity today is attention. There's a lot of content out there. A lot of tweets out there, not all of it gets attention, some subset of it gets attention. And so increasingly our role is moving towards how we recommend content and that sort of, is, is, a struggle that we're working through in terms of how we make sure these recommendation systems that we're building, how we direct people's attention is leading to a healthy public conversation that is most participatory.
