This seems like a wild basis for a hosting policy. It doesn't ban code shown to be infringing, malicious, insecure, or unmaintained. It bans code based on how Codeberg believes it was produced or some individuals at Codeberg believe it was produced.

How would they establish that a project "mostly" consists of AI-written code? Lines, commits, tokens, or architectural importance? There is no reliable detector, and metadata only catches people who honestly disclose their tool use. In practice, this only creates an incentive to conceal AI usage.

Authorship is also a poor proxy for quality. Human-written codebases routinely contain copied patterns, unnecessary abstractions, stale comments, superficial tests, security vulnerabilities, and large subsystems nobody seems to understand. Many mature projects exhibit the exact same problems attributed to LLM-generated code with the technical debt they've built up over time. Slop isn't new or unique to generated code. It is extremely common, especially in beginner, hobby, and abandoned projects which have historically served as a critical part of the open source software community.

The copyright justification is particularly weak. Lack of copyright protection does not make code non-free. Public domain source is still free software. A particular output might reproduce protected third-party code, but that requires evidence about that output. It isn't established merely by showing that an LLM was involved. If provenance were the true concern, then allowing some undefined minority of AI-generated code doesn't solve it. A single copied component can create a real licensing problem. So, the argument immediately falls apart when they qualify it with "mostly".

I don't use Codeberg, so I have no personal stake in this, but I'm surprised its community adopted such a vague and practically unenforceable policy. The argument that Codeberg has limited resources and cannot host endless disposable projects sounds legitimate until you consider how this policy could be enforced. Either someone must investigate repositories and infer their production history from circumstantial evidence, which is expensive and unreliable, or enforcement will be selective and complaint-driven.

If resource consumption, abandonment, or low-effort projects are the actual problems, Codeberg should regulate those observable problems directly though I'd argue targeting "low-effort" projects is as problematic as this policy suffering from many of the same issues. As written, the policy seems more likely to punish honest disclosure than to actually prevent harmful or infringing code.

Maybe this is a fundamental difference in how our societies work, between Germany and the USA. Here, when we go swimming, we leave our phone, keys, and wallets at the beach and just go swimming. It's a trust system, my neighbor won't take my shit because I won't take his shit. So maybe the idea behind the system is to simply ask people who want to upload their slop to not upload their slop, and that that has enough of an impact to be worth doing already.

As for copyright, LLMs can reproduce nearly 1:1 fully copyrighted, non-foss code. I would love to see someone argue in a German court that they can copy a book, a piece of code, or a movie, by laundering it through a program that produces an average of lots of copies of the same movie or book, and burns a lot of power doing it, and that this makes the product of it entirely public domain.
