An illustration (February 2006) of what could happen when an ‘open source’ application is really a front for corporate software. In this case, the claim is that a dispute with Sun has led to IBM creating its own fork of the OpenOffice.org code, called Workplace
The argument is that Sun should transfer ownership of the copyright to OpenOffice.org to an independant foundation.
The source of this ‘rumour’ is here:
OpenOffice … is hoping for some development help from IBM. But IBM isn’t going to contribute to the project as long as Sun Microsystems holds on to the OpenOffice intellectual property.
On the other hand, a follow-up story appears here where everyone says they get along fine really.
