If you use open source code in your company project but do not follow its open source license, even if you have not been discovered, you still have an obligation to proactively correct the mistake and comply with the relevant license regulations. This is a responsible behavior that can avoid legal risks and maintain the company's reputation. Here are some steps you can take: 1. **Review the license**: Understand the license requirements of the open source code. Different open source licenses have different regulations, such as GPL, MIT, Apache, etc. 2. **Remediation**: Take necessary remediation measures according to the license requirements. For example, if the license requires the release of source code for derivative works, make sure you meet this requirement. 3. **Internal reporting**: Inform the company's internal legal or compliance team of this issue for professional advice and support. 4. **Change the process**: Ensure that future use of open source code complies with the company's open source compliance policy to avoid similar problems from happening again. 5. **Education and training**: Train the team on open source license compliance so that every member understands the importance of license compliance. Proactively addressing these issues is not only a manifestation of compliance with legal and ethical responsibilities, but also helps to build a transparent and compliant corporate culture.
