We require that contributors to RPM Fusion (as defined below) agree to this RPM Fusion Project Contributor Agreement (FPCA) to ensure that contributions to RPM Fusion have acceptable licensing terms. Non-Goals
The FPCA is *not* a copyright assignment agreement.
The FPCA does *not* somehow supersede the existing licensing terms that apply to RPM Fusion contributions. There are two important subpoints here. First, the FPCA does not apply to upstream code (or other material) that you didn't write; indeed, it would be preposterous for it to attempt to do so. Note the narrow way in which we have defined capital-c "Contribution". Second, the main provision of the FPCA specifies that a default license will apply to code that you wrote, but only to the extent that you have not bothered to put an explicit license on it. Therefore, the FPCA is *not* some sort of special permissive license granted to any party, despite the explicit choice of a more restrictive license by you or by upstream developers.
