On December 2, 2025, Anthropic acquired Bun, a JavaScript runtime written in Zig. The Zig community celebrated this as validation of the language's production-readiness. But Zig's BDFL maintains a strict no-LLM policy for contributors, while Anthropic's entire business is LLMs. How does a $350B company contribute to a language whose governance rejects their core technology?
Official acquisition announcement from Bun creator Jarred Sumner. Emphasizes continuity (MIT license, public development, same team) while framing deal as infrastructure bet on AI coding tools. Notable for financial transparency ($0 revenue, 4+ years runway remaining) and explicit rationale for abandoning independent monetization path.
r/Zig community split between validation optimism (mainstream adoption proves production-readiness) and enshittification fears (citing Parse, VMWare, Redis precedents). Strategic rationale unclear to technical observers; notable absence of discussion around Zig's no-LLM contributor policy despite AI company acquirer. Community expects ZSF donation as commitment signal.
Concurrent with the Bun acquisition announcement, Zig Software Foundation migrated from GitHub citing Microsoft's AI focus and violations of their strict no-LLM contributor policy. Andrew Kelley abandoned 10 years of GitHub infrastructure rather than tolerate AI feature encroachment, demonstrating the rigidity of Zig's anti-LLM governance stance.
Zig community forum reaction showing cautious optimism: members view the acquisition as production validation while trusting BDFL Andrew Kelley to navigate values tensions between Anthropic's AI focus and Zig's contributor policies.
