Question

Your organization has enabled the setting that blocks suggestions matching public code (the duplication detection filter) for all Copilot users. A developer asks whether this guarantees that any code Copilot accepts into the codebase is free of open-source license obligations and safe to ship in a proprietary product. What is the most accurate response?

Accepted Answer

No — the filter only suppresses suggestions that match a public code corpus of roughly 150 characters; it is not a license compliance tool and does not certify that accepted code is free of legal obligations, so normal review still applies.

Answer

Yes — with the filter enabled, Copilot only produces original code, so no license review is ever needed.

Answer

Yes — the filter automatically inserts the correct open-source attribution and license text for any matched snippet before it is suggested.

Answer

No — the filter must be paired with a separate content exclusion rule on each repository before it provides any license protection.
