It's possible, but there is no advertisements, and most servers are run by volunteers. Right now, with current tech stack, which isn't most efficient I heard Leo Laporte who runs TWiT Podcast network and ~5000 user https://twit.social https://twit.social server it costs him 380 dollars / month for fully hosted using https://masto.host https://masto.host server. Sure it can scale, it's not harder than newsletters, but it needs money, I have serious doubts it can scale without advertisements.
