Review License Compliance of DSFR Drupal Theme

Problem/Motivation

I would like to bring to your attention a potential licensing concern regarding the DSFR Drupal theme. This theme is based on the French Government Design System (DSFR) and is distributed under the Licence Ouverte 2.0. However, after inquiring about its permitted usage, I received clarification from the theme maintainers (see: Issue #3508522 💬 About using the Licence Ouverte 2.0 in commercial projects Active ).
Key points from their response:

The source code (HTML/CSS/JS) is open-source, and anyone can modify and redistribute it.
The DSFR design itself (branding, styles, UI components) is restricted to official French government websites, as per French legal regulations.
While the code can be freely used, only government entities are allowed to use the official DSFR design.

Why this matters:

Since Drupal promotes open-source contributions, it might be important to clarify whether this theme can be listed in the Drupal ecosystem if its intended use is legally restricted. Some key questions for review:

Does this theme’s license align with Drupal’s GPL requirements?
Should there be a disclaimer about these restrictions in the project description?
Would a fork/modification be necessary to ensure compliance for broader usage?

I believe it would be beneficial for the Drupal community to review this to ensure clarity and compliance. Looking forward to your insights!

Thank you for your time.
