Department of Energy has frowned upon using GPL/copyleft licenses historically, presumably around the desire to enable commercialization of a product by any contractor (including DoD). Note that this doesn’t mean you are prohibited from contributing to software with such a license, and an MoU can override such restrictions (that often end up in the site contract).
