A formal announcement of the creation of the Public Domain Software Foundation (PDSF). The PDSF is meant to be a parallel to the Free Software Foundation. It is being started to advocate and support the placement of source code and documentation in the public domain rather than under the GNU licenses. This presentation will include an explanation of how cryptographic management of identity makes many licenses unnecessary. Package and patch management solutions are becoming much more automated with Linux distributions as well as with various software packages. An explanation of why this trend is making the public domain a necessity for many types of modern software.
