Why is snipsnap GPL ?
We decided to use the GPL because we wanted and have to keep the IP rights. But we think that wiki and weblog tools will be a commodity. Money can be better earned from selling support and features-development than licening costs.
SnipSnap is also used as a tool for several of our other research projects.
The prime income of Fraunhofer is consulting, not selling IP rights.
