GPL Violation in Cary Audio DMS-500
Cary Audio sells a product called “DMS-500” which is based on MPD. Their MPD binary has been linked with various proprietary libraries, including the Roon RAAT SDK and a MQA decoder.
After my request for the source code, Cary Audio has sent me a tarball with only a part of the source, and it doesn’t even compile. The most important parts have been ripped out of that tarball. So far, Cary Audio has not replied to my complaint.
According to the GPLv2 section 4, Cary Audio’s license to distribute MPD is terminated. Hence, Cary Audio products containing MPD are illegal due to copyright violation.
