Europe has it's own open-source software license! I started using it, and I want to spread the word
8 months ago by TheDorkKnight to c/europe
TLDR: It's compatible with other copy-left licenses like GPLv3. However, it's available in multiple languages, which technically makes it more applicable.
I started using it for my own project. If you want a practical example: https://github.com/TimoKats/emmer
That's wrong. The EUPL's strictest provisions remain in effect even when used in other licenses:
However, according to the EUPL, the compatible licence that is applied to a derivative work will prevail "in case of conflict" with the EUPL. For example, when the EUPL licensor has its seat in Germany, the applicable law is German and the court is Berlin, but if the code is reused in a French project distributed under CeCILL, the French law will be applicable and the competent court will be Paris. But on the strongest open source EUPL provisions, like the coverage of SaaS and the obligation to publish and share the derivative source code, none of the listed compatible licences enters in conflict with the EUPL: for example, they may not "impose" code distribution in case of SaaS distribution, but they do not prohibit it. Therefore the EUPL obligations are persistent.
The EUPL 1.2 also allows directly relicensing to GPLv3, I don't know where they got the idea you cannot do so.
Large parts of the GPLs are also void (e.g. providing "zero warranty/liability" and provisions regarding dynamic linking) according to EU case law.
The EUPL is effectively a interoperable strong copyleft license. It tries to prevent license incompatibilities due to "virality".
I strongly recommend reading these two articles, they are much more accurate than the FSF's:
Highly interesting. However:
So these are the parts of the EUPL 1.2 that are most relevant to copyleft:
- Obligations of the Licensee
...
Copyleft clause: If the Licensee distributes or communicates copies of the Original Works or Derivative Works, this Distribution or Communication will be done under the terms of this Licence or of a later version of this Licence unless the Original Work is expressly distributed only under this version of the Licence — for example by communicating ‘EUPL v. 1.2 only’. The Licensee (becoming Licensor) cannot offer or impose any additional terms or conditions on the Work or Derivative Work that alter or restrict the terms of the Licence.
Compatibility clause: If the Licensee Distributes or Communicates Derivative Works or copies thereof based upon both the Work and another work licensed under a Compatible Licence, this Distribution or Communication can be done under the terms of this Compatible Licence. For the sake of this clause, ‘Compatible Licence’ refers to the licences listed in the appendix attached to this Licence. Should the Licensee's obligations under the Compatible Licence conflict with his/her obligations under this Licence, the obligations of the Compatible Licence shall prevail.
Having read this section multiple times, also in different languages, I preliminarily believe that the following still remains possible:
Let's say that some person or entity "A" has released some code under the EUPL.
Some other person or entity "B" creates a derivative work and distributes it (including all of A's code) under the LGPL. This is allowed per the first sentence of the EUPL's Compatibility clause above: "this Distribution or Communication can be done under the terms of this Compatible Licence". Here B is a licensee of the EUPL-licenced work, and what the final part of the Compatibility clause (just like the text that you quoted) says is that B, being a licensee of a EUPL-licensed work, continues to be bound by all of the EUPL's copyleft obligations. Fair enough.
Now some third person or entity "C" comes along, and takes just this re-distributed work, which is being distributed by B under the terms of just the LGPL. Here C has no obligations under the EUPL, because C is only dealing with code that is distributed by B under just the LGPL. That is, C is solely a licensee under the terms of the LGPL.
And thus the exploit would be: Corporation C pays some straw man company B to re-distribute A's interesting EUPL code under the LGPL, so that corporation C can pick it up while only needing to comply with the weaker copyleft of the LGPL.

The Free Software Foundation writes the following about the EUPL 1.2 (https://www.gnu.org/...):
The fact that re-licensing from EUPL to GPL is so cumbersome (and therefor off-putting to independent developers), and that at the same time it allows for re-licensing to weaker copyleft (i.e. for derivative works to be more proprietary, so to speak), makes me not want to use it.
