Fortune is the first to report Toyota’s startling move.

OIN pursues a variety of strategies aimed at protecting the users and developers of such software against the threat of patent suits by proprietary software manufacturers, like Microsoft and Apple. Such suits, if successful, could deny users the freedoms that make open-source software desirable. That Toyota would now join the group reflects the growing importance that software is playing in cars, and the growing number of automakers who believe that open-source software is the best approach to providing many of the needed solutions for its vehicles...
