I was just reading the Magento Commerce Software License Agreement v1 today. (https://magento.com/sites/default/files/magento-commerce-software-license-agreement.pdf)
Under the section 2B, it says
Customers shall not (g) use any Copyleft Software in connection with the Software
Does this mean I cannot use any open-source modules or extensions on Magento Commerce? As far as I know, all popular open-source licenses like OSL are copyleft.
