Moderation would become a nightmare since a private business's right to remove certain content wouldn't apply and now what do you do when a mod or /r/buyitforlife takes down a post that doesn't support the type of coffee maker that like, or whatever a shady reddit mod does these days. I also would rather not post or log into any government run social media, that's seems like a big no from me. I really don't know what a fix would be but I would be interested to see how a government ran social media would look, even if I wouldn't use it.
