i can't speak to gitea, but github and gitlab are explicitly mentioned as having a license in their policy:
> Please be aware that GitHub and GitLab are exceptions to this Policy because they are subject to explicit licensing arrangements that pre-date, and thus take precedence, over this Policy.

GIT is a trademark of Software Freedom Conservancy and our use of “gitea” is under license.
