I think it's more fair to say that someone shows that a contributor has started to commit much more frequently and constantly breaking things, and that this corresponds to when they have started (self-reportedly) using LLM's for development.

Fair enough - my initial comment talked about quality, but I realized that was my own take on the situation.

I had revised the comment because I think I now understand Drew's chief complaint to be about the moral side of LLM usage, not the practical quality side of LLM usage.

He does use the word "slop" which implicates quality, but that's a single word in his essay, versus whole paragraphs about the moral questions of LLM usage and his stated reason that the fork was "to keep my conscience clear".
