The source code for nginx is hosted in the US, BSD-licensed and has the american F5.com as the primary maintainer, sponsor, and steward of NGINX.
In 2022 some of the developers forked it into Angie, the code of which is hosted in the US as well.
In 2024 one of the lead developers forked nginx into freenginx due to F5’s interference, bringing it more in line with its initial grassroots origin. They have a self-hosted Mercurial repo (and a mirror in the US) and the domain seems to be controlled by the lead developer.
Heretic!
