Please don't take this the wrong way, but the Fediverse seems like a great foundation on which to build a sustainable Internet economy.
Think about it: the Fediverse encourages self-hosting, so a hosting company specialised on Fedi software and hardware needs could be profitable. I know there's already at least one project like this.
What about #PeerTube? Authors in the same area or with similar creative itches could set an instance up, share costs and monetise it with donations or sponsorships. Same could be done with #Funkwhale for podcasts.
Microblogging and blogging platforms can be used to publicise and discuss such projects.
Every step of the supply chain can be independently funded and managed without external interference from BigTech companies.
I think there is certainly a need to help people either host their own instance, either via managed hosting (what https://masto.host/ are doing) or helping people find hosting and set up a domain and instance,
But it needs to be affordable for people, perhaps also need to help people develop the skills to do that via teaching, so as companies or at least small businesses take up Mastodom they can find people with a) the skills to host an instance but B) they have the knowledge of the culture here so that can be successful.
Do so by using privacy friendly DNS and other services as in not cloudflare.
