> "Facebook is a private company, it can do whatever it wants on its platform," I think it's important to distinguish between the legal right for a company

I'll go a step farther. For those who say "facebook is a private company, it can do whatever it wants"... does that include taking a completely hands-off moderation policy? I'm pretty sure that the answer is no - because the U.S. government will step in if they try. They're already in legal trouble over the Myanmar/Rohingya thing - what we're seeing is not Mark Zuckerberg standing up for his moral principles. What we're seeing is government coercion.
