I'm pretty sure based on your answers you have no idea how things work in the real world. Reading "The Lean Startup" or "The Art of the Start" doesn't really qualify you to make such nonsensical statements about how a multi-billion-dollar publicly traded company should behave. A startup burning through $10M of VC funding is completely different from a publicly traded company burning through $2B in funding. You can't even justify it at this point. Tesla Energy is a dream, you can't waste $2.6B on an unproven dream and then buy a completely unprofitable cash-bleeding company when you yourself are bleeding cash. He needs to have much better sense than that as a CEO, his duties to his shareholders demand it.
