If I was a Twitter or Facebook investor, I have one question: What did you expect was going to happen? Honestly. Did nobody have the foresight at Facebook or Twitter to think that this wouldn't blow up? Did nobody think, just once, that this might invite regulatory action or be in news headlines? And if honestly nobody thought this might happen, I'd want the entire management and "safety" team replaced for having no…
This post has a very odd tone, as if a private company enforcing their policy to remove unverified & leaked personal correspondence of a private citizen is some unquestionable moral wrongdoing that's apparently going to blow up. Surprised to see this as at the top, on HN. National Review is a conservative wing-nut website trying to turn this non-story into fuel for their censorship culture war.
If this was published at any other time (and the material for the story has apparently existed since December) the public and the professional media would have had time to scrutinize it, discuss its shortcomings, etc.
But, as Winston Churchill said "A lie gets halfway around the world before the truth has a chance to get its pants on." We can't do that and being complicit in spreading misinformation in the middle of an election is, I'm sure, still a strong memory that social media companies have from the 2016 election.
My guess as to how this will go is that it will take a week or two to authoritatively discredit the article, but by then, if left unchecked, the article will have already done its damage. The cynic in me says that the originators of the article already know that there isn't much truth here and that this is the point of releasing it while people are voting.
