I've never been near code handling money, but "never put anything in writing that you wouldn't want to see in the New York Times" is something I've heard repeatedly at a big tech company too. It seems like pretty standard advice nowadays. The "move fast and break things" slogan was by Zuckerberg at Facebook, though they've since abandoned it.
