NBIA Data Retriever open source?

Yes! The NBIA Data Retriever, like the backend server it talks to, is licensed under the 3-clause BSD license, sometimes referred to as the 'new' or 'modified' BSD license. The BSD license is very permissive, business-friendly, and approved by the Open Source Initiative. The source code is available from GitHub in the CBIIT/NBIA-TCIA repository, specifically in the software/nbia-download-manager subdirectory. Developers are free to review or fork to create derivative works. Of course, we would appreciate, but do not require, pull requests back to the repository if you have created nice new features or bug fixes that others might benefit from. They would be reviewed by the NBIA development team for inclusion, possibly after some tweaks, back into the main repository.
