I am working for a service company. As per client requirement we need to slightly modify eclipse mosquito source code. It is dual licensed with EPL and EDL. (https://github.com/eclipse/mosquitto/blob/master/LICENSE.txt).
In the License FAQ it says user can select the license(https://www.eclipse.org/legal/eplfaq.php#DUALLIC) .
As EDL is more permissive and BSD like (https://www.eclipse.org/org/documents/edl-v10.php), we choose EDL license. Now can we use modified mosquito without opensourcing our modifications? Is there any other implications which will impact it's commercial use.
