Winamp published their code as "open source". Problem is...
- It wasn't open source, it was proprietary but you can see the source code.
- Their custom license didn't even allow forks, which is against GitHub TOS
- The codebase apparently contains proprietary code from third parties that they don't have the right to relicense.
- The codebase apparently contains GPL code from third parties that they probably didn't have the right to make proprietary in the first place
I don't exactly consider Drew Devault a reliable or unbiased judge of character
