Tbf I guess as a popular open source project not using AI to fix bugs, they probably already have more open bugs than they can ever fix so it doesn't really help them for people to find more.
I would imagine his bug was actually ignored just because Zig has 2700 open bugs, rather than some AI policy violation.
Show me a popular open source project that doesn't have a large number of open issues and I'll show you one that has a triage bot auto-close them.

They may just be taking the slow route of rejecting by default until they can be sure that the usage of LLMs provides long term value. I don’t see anything wrong with that. If you’re writing robust software, using LLMs at this stage is a bit of a gamble. We don’t fully know the long term effects on code quality yet.
