I'm not the OP, but I would personally say that not wanting to work with LLM-generated output (including that submitted via PRs and issues) is reasonable, but not wanting to use LLM-generated code from well-regarded established projects (not vibe-coded slop) is veering closer to tribalism.

Because to me, it's entirely fair to care about the process when you're the one working with it, but if you've never looked at the code and it works well, it seems odd to care how 10% of it was produced.

I still wouldn't quite use the loaded "tribalism" term here myself though, because there are still a few valid reasons to be skeptical of LLM-generated code, but for many people, their hard anti-LLM stance appears to be more of a shibboleth than a principled stance from my perspective.
