Host the git repo on sites other than GitHub if it's not already.

Not to sound too conspiratorial, but it might not be the best idea to have a piece of software that's anti-corporate by nature, and only have it hosted on a site owned by Microsoft.

Sounds reasonable.

If GitHub stays main and the other origin is only kept as backup it would be easy keeping them in sync with some actions.

Agreed with @kwitsch, GitHub must stay the main repository with PRs, build actions etc. We can just mirror the git repo. I would suggest to take some non-commercial provides, like codeberg (https://codeberg.org/) and not GitLab/BitBucket etc.

Docker images are already mirrored (main is docker.io, mirror is ghcr.io).

sourcehut.org is another good one which I believe is non commercial.

I created a mirror on codeberg, since I already had a user: https://codeberg.org/0xERR0R/blocky
