The relevant part is towards the end:
To reach an ultimate level of efficiency for Codeberg, I expect we require times 5 to 50 our current user count, that is 100k to 1 million. And if you fear the monopoly: this still leaves room for 73 to 730 instances if we want to replace Microsoft GitHub alone.
So I really hope we can get there, with a federated Gitea hopefully coming soon. With proud self-hosters forming associations and non-profits, to combine the forces and provide better service. Platforms that are owned by users, doing the best for them, and not for investors.
