Germany and the EU will probably kowtow to the US if the DMCA requests or lawsuits are brought by big enough players.

Big money interests rub shoulders with US politicians, US politicians deal with their overseas counterparts. Therefore, big enough DMCA requests will be mentioned behind closed doors in the same breath as international trade and other geopolitical concerns. Money protects money in deals between close enough friends and allies.

If Codeberg were based in Russia or a US geopolitical adversary, on the other hand, such requests would likely be ignored.

A DMCA takedown is targeted at the host and is a pre-lawsuit thing ("we claim X and if you take it down now your host is safe" via the DMCA Safe Harbor provisions). If they escalate to lawsuits then not sure it's significantly different in Germany vs the USA. It's not like Europe is free from things like blocking all of Cloudflare because the football league wants to.
