This is really strange!
Chromium Legacy is an up-to-date fork of Chromium which supports back to Mac OS X 10.7 Lion (from 2011). On Friday, the developer's Github account and all of his repositories suddenly disappeared. The links now return 404 errors.

Today, the same thing happened to Supermium, an equivalent project for Windows which supports back to XP. To my knowledge, the developers of Chromium Legacy and Supermium are wholly unaffiliated.

Does anyone happen to know what the heck is going on? It's a little scary and makes me not want to trust GitHub. I don't see anything relevant in GitHub's repository of DMCA notices[1], and I'm having trouble coming up with legal grounds on which such a takedown could happen.

You can add push URLs to your origin branch such that `git push` automatically mirrors your code on multiple remotes: `git remote set-url --add --push origin git://another/repo.git`. If you maintain an open source repository, I would encourage you to have mirrors across gitlab, codeberg, and/or a self hosted gitea instance.
