Good read, nice reminder of one the reasons why a lot of LLMs have similar stylistic choices especially in earlier generations with the formatting and emoji usage. Although I do see newer frontier models have been more aggressive with dealing some of these issues. For example, Opus 4.5 these days seemed to not be as wordy and tells you you’re stalling, just ship it or send it etc. But some open source models trained to game LMArena might keep exhibiting the characteristics mentioned in the article.
