DMCA only works in the United States.

The Darknet Diaries episode on the Pirate Bay [1] touched on the long tentacles of US copyright law

Does it? It's obviously US legislation, but I'd wager there are trade agreements between EU (or others) and US that require the EU to honor this legislation.

Not the DMCA but local copyright laws.

But since this is not an actual copyright issue, you just need someone to tell google that the revanced code is not copyrighted by google.

(unless there was any copyrighted material in the repo, then it's a different story)

Radicle, then? Or more simply self-hosted gitea on an ENS domain?

Pick a European hosting provider that knows what they're doing and they're more than likely to ignore DMCA claims as they aren't legally binding in the EU

Europe can be even worse - in Germany, we still have the legal concept of Störerhaftung around that can expose hosters to significant legal liability.
