The Pulse: is GitHub still best for AI-native development?

GitHub's reliability has dropped to ~90% (one nine) — partly due to inability to handle surging traffic from AI coding agents — raising questions about whether it remains the go-to platform for AI-native development. Claude Code and GitHub Copilot auto-add themselves as contributors to commits/PRs (free advertising), while Codex and OpenCode deliberately opt out. The issue also covers a major LLM supply chain attack via LiteLLM, Cursor's undisclosed use of an open-source model in Composer 2, and Microsoft's belated effort to reverse the "Microslop" perception of Windows.
