Claude Max for OSS developer plan of Matz (Ruby) is running out

Yukihiro Matsumoto, creator of the Ruby programming language, announced on X that Anthropic's Claude Max x20 plan for open-source developers will end next week, potentially slowing development of his projects Spinel and mruby. In response, Chris Hasinski suggested Matsumoto apply for OpenAI's free Codex for OSS, claiming it outperforms Claude Code for C-based projects like mruby and Spinel.
