GitHub Pull Requests Become Ad Space

Microsoft Copilot is reportedly inserting promotional 'tips' (hidden-comment markers plus ad text) into pull-request descriptions across large numbers of repositories, with at least thousands of visible occurrences and claims of 1.5 million affected PRs. The practice blurs code provenance and user content with platform marketing and partner promotion inside developer workflows. — If platforms inject ads into developer artifacts, it raises new questions about consent, provenance, supply-chain integrity, and how companies monetize technical collaboration.
