Comment 8 for bug 1314402

Hmm.. I pointed out the license ambiguity, and one thing they did as a result was adding the GPL license to

http://sourceforge.net/p/skypeinyourlang/code/ci/master/tree/

But the most important evidence would be the wording they added to the overview pages, e.g.

https://www.transifex.com/projects/p/skype-translation-project/

I now realize that you need to be logged in to see it, and if you are it says:

"By contributing to this project, all translators agree to allow us to distribute both their .po files and .lang files under the terms of the GPLv3. Doing this simplifies the work of downstream package maintainers who wish to include the translations in various Linux distributions."
