That won't be easy because Codeberg follows German law.

And German law is more restrictive than U.S. copyright law, with fewer protections for content uploaders and service providers. There is also no concept of fair use that limits copyright.

I want Codeberg to succeed, but running an open code hosting platform (both in the sense that anyone can create an account, and the service source code is publicly available) in the European Union, and especially Germany, is extremely challenging from a legal perspective. Sadly, once they become successful and popular, they will have to implement all kinds of weird stuff, like proprietary scanners for potentially infringing content prior to publishing it.

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.
