The burden of proof is on the person making a positive claim. So I didn't think I really needed any more argument than "the article's argument is insufficient for me to believe their claims". I wasn't trying to make any more general point about censorship or social media.

I don't have a problem in general with a ticketing system for the government to request specific kinds of moderation. There do exist valid carve-outs of free speech, and I see no reason why government and industry couldn't collaborate on that. If it were used to censor political speech, then yes, I would have a problem with that. But I haven't seen evidence of that.
