You should have received a copy of the GNU Affero General Public License

The hardware interface and its sources are published under a Creative Commons License CC BY-NC-SA 4.0. This means you can fork the project, but you must cite the sources and author, while retaining the same or a similar license. Any commercial use is forbidden without explicit authorization.

Commercial

This is to limit the uses integrated in proprietary devices whose vendors would not participate in the project in a fair way and who would otherwise be guilty of any violation of the Libre-Printer license as well as of the free software used by Libre-Printer itself.

With such a license you maintain full ownership and control over your products, while allowing you to distribute your products to customers as you wish. You are not obligated to share your proprietary source code and this saves you from having to conform to the requirements and restrictions of the AGPL.
