One of the things that Eben Moglen has impressed on me when I've talked to him was that he - and Richard Stallman - have always preferred to negotiate settlements in cases of alleged breaches of the GNU GPL, rather than to rush to litigation. Hitherto, that's always worked, in the US at least. So it's extremely significant that Moglen's SFLC has decided to change tactics:
The Software Freedom Law Center (SFLC) today announced that it has filed the first ever U.S. copyright infringement lawsuit based on a violation of the GNU General Public License (GPL) on behalf of its clients, two principal developers of BusyBox, against Monsoon Multimedia, Inc. BusyBox is a lightweight set of standard Unix utilities commonly used in embedded systems and is open source software licensed under GPL version 2.
One of the conditions of the GPL is that re-distributors of BusyBox are required to ensure that each downstream recipient is provided access to the source code of the program. On the company's own Web site, Monsoon Multimedia has publicly acknowledged that its products and firmware contain BusyBox. However, it has not provided any recipients with access to the underlying source code, as is required by the GPL.
Clearly something big is afoot, here. Perhaps Moglen thinks the time has come to establish the legal solidity of the GNU GPL once and for all, and that this is the case to do it with. It will certainly be fascinating to see how this plays out.
