The most human thing is posting something that breaks the rules.

It's a reference to a very old meme. Where "eat the bugs" was a shorthand for the lower classes being fed bugs as a cheap source of protein. Has been re-mixed without attribution so many times that I don't know when it started, even Snowpiercer got in on it back in 2013. https://www.youtube.com/watch?v=J_jK9O4tEiA

I think here it's meant to imply that LLMs will be forced on the population at large as a form of social control.

Presumably that HN has an automated LLM-based filter to moderate rude or irrelevant comments, which is a little irrelevant to the article's wish not to see generated posts or comments, and not without its own problems besides: ML is necessary for large-scale moderation, but there are guidelines (like "don't post AI-generated text") which are IMO necessary but also just definitionally hard to enforce in an automated fashion

That your comment and article will be subject to the ranking and processing of a machine authority and there is nothing you can do about it. So you might think you’re being flagged or shadow banned because someone downvoted you or otherwise. But no, it was an automated process that did it.

If it makes the author happier they can ask dang what is the prompt used for automated HN processing.
