" When Musk announced in 2014 that Tesla would open-source all of its patents, analysts tried to decide whether this was a publicity stunt or if it hid an ulterior motive or a catch. But the decision was a straightforward one for Musk. He wants people to make and buy electric cars. Man’s future, as he sees it, depends on this. If open-sourcing Tesla’s patents means other companies can build electric cars more easily, then that is good for mankind, and the ideas should be free. The cynic will scoff at this, and understandably so. Musk, however, has been programmed to behave this way and tends to be sincere when explaining his thinking—almost to a fault. "
