This is wild. Facebook "blocked" a project I was part of in 2018, basically a website where you could see if you'd been exposed to Russia-backed disinfo on Facebook. Facebook blocked the site, and when I mentioned that fact to a reporter on Twitter, Mosseri came up with the same excuse.

Tweets are no longer up, unfortunately. (Didn't survive my last mass deletion.) But @greene.haus@justinhendrix.bsky.social@espiers.bsky.social, and a few others should also remember and be able to confirm those details. Reading Adam's message feels like déjà vu.
