Skype violates open source licence
Linux fundamentalist strikes again
Skype has been convicted of violating the open source GPL (General Public License) by a regional court in Munich.
However, it is not its popular peer-to-peer VoIP software that was addressed in court, but a VoiP phone from SMS Networks that the firm sells on its website.
The phone uses the Linux kernel, but Skype failed to also supply the source code, a prerequisite of GPLv2. Skype did, however, issue a flyer that contained URLs to the GPL license and to the source code. The GPL only permits a URL for software that is delivered over the internet.
The plantiff was German open source purist and Netfilter developer Harald Welte, who also runs gpl-violations.org, an organisation he set up to track down and prosecute violators of the GPL. In 2004, Welte sued Dutch company Sitecom, alleging it used the software in a wireless network product without abiding by the terms of the GPL. Not a word about the new case on his weblog  yet.
Exactly what punishment Skype can expect is not clear, but it's likely to be a small fine. ®
