The story of Berk, an experienced software developer at TrapDoor Inc., serves as a cautionary tale about the importance of proper licensing and adherence to copyleft licenses in open-source projects. The project's high-level design was approved, but it wasn't until the code review that the team discovered the heavy reliance on a GPL v3.0 licensed dependency, which led to significant issues with attribution and compliance. As a result, trust was lost, the six-figure project was canceled, and the customer refused to pay, highlighting the importance of proper licensing in software development.
