Descriptive Quote from the OSOpinion editorial: “Open source and free software were founded on the idea that all information and knowledge should be made freely available for the benefit of all, and what is software but the embodiment of knowledge? Unfortunately, much of today’s open software is not free in one important respect. The use of copyright and the General Public License (GPL) restricts its commercial exploitation.”Our Take: Personally, I object. While the Public Domain license feels and sounds more “liberal” than GPL itself, it has a very dangerous legal catch. Sometimes people use the term ‘public domain’ in a loose fashion to mean ‘free’ or ‘available gratis’. However, ‘public domain’ is a legal term and means, precisely, ‘not copyrighted’. And when you release software on the wild, under a Public Domain license (not copyrighted and without any accompanied warranty that is), the state can file a lawsuit against you if they wish, for any (even small) bugs they may find. This is why there are ‘public domain’-alike licenses around (truly liberal), but without the catch: the BSD license for example.
