VS Code Silently Tags Commits with Co-Authored-by Copilot Even Without AI Usage

What Happened
GitHub PR #310226 revealed that VS Code appends Co-Authored-by: GitHub Copilot to commit messages even when no Copilot feature was used. The story hit near the top of Hacker News with over 680 points.
The Broader Issue
Co-authorship metadata carries legal meaning in open-source projects. When an AI tool inserts itself into authorship records without explicit action, it pollutes that signal. Developers are demanding opt-in rather than opt-out for AI attribution in commits.

VS Code automatically injects Co-Authored-by: GitHub Copilot into git commits even when users never used Copilot, sparking backlash on Hacker News.
Why it matters: agentic coding stops looking cheap once billing follows actual token burn. GitHub says all Copilot plans switch on June 1, with monthly AI Credits replacing premium requests and a preview bill landing in early May.
Hacker News did not focus on the headline that plan prices stay flat. The thread zeroed in on a simpler point: on April 27, 2026, GitHub admitted that long agentic coding sessions cannot be subsidized forever, and predictable Copilot costs are giving way to token math.
