It seems to me, Codeberg sees no value in AI slop and doesn't want to spend significant amounts of its limited resources hosting it.
The author talks a lot about what they want from Codeberg. And I suppose it's fine to wish someone (on the right side of the ocean) would provide services, tailored to your personal desires, for free. But don't be surprised when no one takes you up on it.
For myself, I don't see a point to Codeberg simply being a clone of GitHub. GitHub is free, which is great, but it's also pretty shitty. Why do we need more of that?
