I may be a little late to the game, but if you use GitHub and haven't done this yet, your code is being used to train Microsoft's AI models RIGHT NOW. Let me say this another way... Microsoft is training their AI to steal your code.
Since April 24th, GitHub has been collecting your code, prompts, file context, and repository structure from anyone on Copilot Free, Pro, or Pro+ plans — and using it to train their AI. This includes code from your private repos whenever Copilot is active. They turned this on by default without asking.
To opt out:
- Go to github.com/settings/copilot/features
- Under "Privacy" find "Allow GitHub to use my data for AI model training"
- Set it to Disabled
Better yet, uninstall the Copilot extension from your editor entirely. As long as it's running, your code is being sent to their servers.
This isn't hypothetical. They're collecting inputs, outputs, code snippets, comments, file structure, and surrounding context — basically everything that makes your codebase yours. And yes, they share it with Microsoft. Please pass this on.
