Quoting Andreas Kling

Ladybird will stop accepting public pull requests, citing changed trust assumptions in the age of generative AI.

Simon Willison quotes Andreas Kling explaining Ladybird’s decision to stop accepting public pull requests. Kling argues that large patches once implied substantial effort, which could serve as a proxy for good faith, but generative AI has weakened that assumption. His central point is not whether code was typed by hand, but who takes responsibility for code once it enters a browser intended for real users.

This short post by Simon Willison primarily quotes a passage from Andreas Kling in Ladybird's official article "Changing How We Develop Ladybird." The Ladybird project has announced that it will no longer accept public pull requests, and the reason behind this is tied to how generative AI is disrupting the trust model of open-source collaboration. Kling points out that in the past, a large patch usually meant the contributor had invested considerable time and effort, so this investment itself could be treated as a kind of proxy indicator of goodwill and reliability; but now that AI-assisted or AI-generated code has become easy to produce, this assumption no longer holds. In other words, project maintainers can no longer rely solely on the size or surface completeness of a patch to infer whether the contributor truly understands the changes, whether they are willing to be responsible over the long term, or whether they are clear about its side effects.
