This is interesting-Go Elon---------------
Musk hasn't turned a profit on any of his ventures. Most of his cash is from taxpayer funded subsidies and grants. A major portion of the funding for his R&D comes from the gov't.
You notice how he threw a hissy fit over the U.S. backing out of the Paris climate deal? He claimed it would cost thousands of jobs and lost tech. Think about what jobs and tech that is. Out of the trillions promised, billions would go to his green energy companies and ultimately we would/will/are paying for it. A true innovator would put his own butt and bankroll on the line. He's a modern P.T. Barnam.
Oh, and he isn't sharing that tech for free.
