More than 11,000 GitHub projects affected: Copilot posted ads for Raycast

The incident was first noticed by software developer Zach Manson, who wrote about it in a blog post. Calling the situation “horrific”, he said he didn’t expect such behavior from the platform. After a member of Manson’s team had asked Copilot to correct a typo in a pull request, the AI assistant went beyond generating the requested code and added a note referencing Raycast and Copilot. Following his report, more developers came forward with similar experiences, with many considering it a form of advertising on GitHub.

Microsoft has issued a statement in response to the criticism, denying any allegations of intentional ad placement. According to the company, the incident was not part of a planned marketing campaign but rather was due to a bug in the program logic that caused these notes to appear in the wrong places. A Microsoft spokesperson confirmed that GitHub has no plans to integrate advertising into pull requests. The messages in question were originally intended to appear as product tips only in specific contexts. As a result of the software error, however, they were mistakenly inserted as footers in pull requests.

The “advertised” Raycast is a search tool for operating systems such as macOS and Windows. The Raycast team has likewise issued a statement denying any co-marketing partnership with Microsoft. Microsoft further confirmed that the issue has been identified and that the feature has been updated to prevent such messages from appearing in the comments of pull requests.

Responding to Notebookcheck's inquiry, GitHub reiterated that it has no plans to introduce advertisements on the platform. The error in GitHub Copilot has since been resolved.
