The author is worried about the future of Bun, a JavaScript runtime, after its acquisition by Anthropic, due to concerns about Anthropic's handling of its other product, Claude Code. The author believes that Bun is still a great tool, but is concerned that Anthropic's policies may negatively impact its development. The author has decided to move some projects away from Bun and recommends using pnpm instead. The author hopes that Bun will continue to be well-maintained and improved.
