"Forgejo was initially created in December 2022 as a fork of Gitea. The fork occurred after a for-profit limited corporation ran by the lead maintainer of the project, Lunny Xiao, silently transferred Gitea's trademarks and operations to the company and began to establish an open-core model."[0]

EDIT: HN discussion on the latter: https://news.ycombinator.com/item?id=33372471

From a quick web-search: Apparently it was an open-source community project, but the governing organization created a for-profit entity and transferred most of the assets to that entity (brand, website, etc.). Gitea apparently still uses MIT licenses, but the community felt it was a betrayal of the open-source ethos. forgejo is a community fork of Gitea when the issues mentioned were not suitably resolved.
