As you may recall, a few weeks back, Twitter made a decision to add a fact check to some tweets by President Trump, and a few days later, to put a label on some of his tweets, saying that they violated Twitter's policies, and would normally be deleted, but Twitter decided that given the newsworthiness of the speaker, they would be left up (though without the ability to comment or retweet them). The president reacted about as well as expected, meaning he whined vociferously, and eventually issued a silly executive order.

Of course, the other end of this story was that Trump posted some of the same content to Facebook, and Facebook chose to do nothing. Indeed, Mark Zuckerberg pulled out this ridiculous self-serving, sanctimonious nonsense about how Facebook would allow that content because he didn't want to be "the arbiter of truth." Except, of course, Facebook does fact checks and content moderation all the time. This seemed to be a lot more about currying favor with the president, than any principled stand.
