I don't disagree with the main point, that the three companies has benefited from subsidies. But it's framed as if this is unique, where in reality you'll find subsidies in these (and many other) industries.
# Cars
GM, Chrysler etc. bailed out for $85B. Sector subsidized in other ways too.
# Space
Most of the space industry is paid for by various governments (some satellites are the only exception). NASA is about half of SpaceX revenue, certainly a large chunk.
# Energy
IMF recently released a report[1], where fossil fuel subsidies are estimated at $1.9 trillion. Other types of energy are subsidized too, solar in China, nuclear in France, etc.
