Musk is very typical of the Silicon Valley technolibertarian mold. He was happy to take a $465 million government loan for Tesla Motors, then soon after paying it off, he was more than happy to speak out against government subsidies like the one he just paid back. This has been Silicon Valley’s modus operandi for years, of course: promoting the tech sector’s independence from and superiority to mundane governance, while relying on it. In a nutshell, this is the reality behind the myth of the “free market.”
The author doesn't understand the hidden subsidies on fossil fuels. If we were to bake in the cost of climate change and pollution into the price, solar energy would have never needed subsidies. And what is Musk supposed to do? Ignore and reject subsidies that are available? The author is grasping at straws here and should have done more research.
