> commercial proprietary software is the "normal" path and we need all these justifications / answers for OSS

When you purchase commercial proprietary software (especially, I think, on the DoD scale) you purchase commercial support and put liability and responsibility on some other entity. If you use open-source software, you only just get the code without any guarantees.

As much as I love using open-source dependencies as a developer, I completely understand why a company or a government agency prefer the proprietary path.
