I saw the press release as more directed towards average automobile buyers. As a "We will not be the ones preventing your favorite Automobile manufacturer from producing an Electric Car in the style you want, and neither will the research cost of the technologies we use".
I believe the message was phrased in a way to be directed at consumers so that hopefully the consumers will send a message one way or another to the other manufacturers causing them to come to more official agreements with Tesla. (which will of course have terms).
