> Codeberg is just a nice logo wrapped around Forgejo/Gitea.
Not true. Codeberg is first of all a downstream fork [0] of Forgejo, making adaptations for high-scale use. And it offers additional services that Forgejo does not offer. Then it has a full-blown non-profit organization around it that enables community participation. It is the presidium of the community members that decided on the new ToU.
Forgejo is a hard fork of Gitea with a GPLv3 license, instead of MIT. Codeberg used to be based on Gitea, but it no longer does for many years now.
