The no-AI policy of the Zig compiler project is for the compiler, other projects can do whatever they want.
Bun's fork of Zig was just an unsound hack that at best would have produced a strictly inferior speedup compared to our current work with incremental compilation, which is already plenty usable:
- June 2025 core team starts using it with the zig compiler itself https://ziglang.org/devlog/2025/#2025-06-14
- April 2026 https://ziglang.org/devlog/2026/#2026-04-08

It's literally an issue with our business model to mess with our contributor pipeline, can't get more concrete than this.

Well, presumably they want to contribute to the compiler. I know that you did not like those contributions, and that view seems entirely valid, but obviously "no AI" rules out their development model (by design, and you likely think that's good, and maybe it is!).
Not intending to defend the bun move, but obviously a project using Zig and also using AI might feel motivated to avoid Zig since they're ruled out as contributors.
