You both are correct.

But also keep in mind in 2004 the legality of many open source projects was not really tested very well in court. Pretty sure that was right around the time one of the bigger linux distros was throwing its weight around and suing people. So you want to ship on PS2 and XBOX and PC and GameCube. Can you use that lib from inside windows? Not really. Can you build/vs buy? Buy means you need the code and probably will have to port it to PS2/GameCube yourself. Can you use that opensource lib? Probably, but legal is still dragging its feet, and you get to port it to PS2. Meanwhile your devs need a library 3 weeks ago and have hacked something together from an older codebase that your company owns and it works and means you can hit your gold master date.

Would you do that now? No. You would grab one of the multitudes of decent libs out there and make sure you are following the terms correctly. Back then? Yeah I can totally see it happening. Open source was semi legally grey/opaque to many corporations. They were scared to death of losing control of their secret sauce code and getting sued.
