Although there is no commons alternative, there is Sourcehut - run by a team that is dedicated to the principles of free software. I should be giving them the money that I spend on GitHub.
At the very least, I should be giving them more money than I give GitHub... I will do that immediately.
Sourcehut is also subject to US law and would have to take down your project if this company files a false claim against you. The problem in this case isn't GitHub, it's the filing of false DMCA notices. And that's not solely a US problem, it can happen in the EU as well.
