People keep bringing up your point 5 here. Almost every other comment seems to parrot this idea that there is some paragon of free speech that Twitter doesn't achieve. Setting all the discussion of what free speech should be, aside, I don't see people making the point that Twitter's huge success as a social media platform may actually relate to their moderation policies. Twitter was found to be more resistant to fake news than other social media sites. I don't know whether this relates to the public nature of tweets or their moderation. Twitter's moderation policy may exactly be the reason the platform has done so well, and rather than clamouring for Twitter to change, I'd suggest that we allow the free market to allow another platform with different a moderation approach to compete.
