The EUPL has network protection, but it can be circumvented pretty easily. That’s because the EUPL also has a clause which lets you convert EUPL code to any of a long list of “Compatible Licenses”, including GPLv2, GPLv3, and many others. So you can just convert to a license without network protection and use the software under those terms. (Technically you can only convert when distributing a derivative work “based upon both the Work and another work licensed under a Compatible Licence”, but you can just find some GPL-licensed function which can be put somewhere in the codebase. Oh, and you may need multiple people to pull this off.)
