While I don't doubt the truth of this story, I wonder, how easy would it be for a platform to make up an interaction like this? Let's say I was making a free speech platform, and it was relatively unknown. If I claim I got a letter from the government asking me to do something anti-free speech, I could make a big deal about how I'm going to ignore that. Even if I made up that letter, would the government ever publicly state that the letter is false and they never sent it?
