Jim Brandt writes in the TPF news blog that the Perl Foundation is helping a court case surrounding the Artistic License. A Java project has adopted the Artistic License and is now in the middle of a legal battle that could be important legal precedent for future cases regarding open source licensing. TPF has helped support an amicus curae brief in the case.
Jim's article notes "the argument [in the case] that there can be no remedy to a copyright holder who chooses not to charge money for their work." It's kind of like how puzzled relatives ask why me work on open source projects if I'm not getting paid to do it, as if it's less worthwhile that there's no money (directly) changing hands. Here, the plaintiffs in the case are trying to make that perception into settled case law. Thanks to TPF for their work here against that happening.
