As for Musk, of course, he is a major crony capitalist; his business wouldn't exist without massive government support.
You seem to think that any business which takes advantage of government incentives involves cronyism. You are wrong. Elon Musk is the exact opposite of a crony capitalist. Elon Musk wasn't supposed to happen at all. He grew up in South Africa, and wasn't even a US Citizen until 2002. He had no US cronies whatsoever because he didn't live here, and he had no South African cronies because he was severely bullied as a child, to the point of being thrown down stairs and beaten unconscious. He was beaten by a bully and his cronies, which doesn't happen to people who have cronies of their own.
Elon Musk is an upstart immigrant entrepreneur who succeeded despite the best efforts of the crony capitalists to prevent it. Those automotive incentives Tesla Motors has taken advantage of were meant for GM and Ford, purely as window-dressing. GM and Ford were trying to greenwash themselves, and firmly believed that in their capital-intensive industry no brand new company could possible grow big enough to compete with them and actually qualify for those subsidies. The NTSHA safety testing regime was meant to be too difficult and too expensive for any tiny little startup to afford, let alone pass, let alone pass with a better rating than anything GM or Ford had on the road.
The people who run GM and Ford got together with their friends from prep school (their cronies) who had been elected to government to do a little harmless PR so they could fend off the environmentalist lobby a few more years. They knew no one was going to actually use those incentives because they knew they were the only ones big enough to be able to use them and they had already agreed not to actually use them at all. But it's illegal in the US to pass laws to benefit or harm specifically named entities, be they natural or artificial persons, so the law had to be written nominally generically, as these things always are, but with attempts at specificity that should have excluded anyone but the intended recipients. That's how actual crony capitalism works. Elon Musk was never supposed to be able to use that money, and especially not to use that money to prove that GM and Ford are liars when they had spent the previous three decades claiming it's impossible to make an electric car people would want to buy.
It's even worse with SpaceX. Before the creation of SpaceX, the United Launch Alliance was an illegal monopoly launch provider who had managed to push the price of a single rocket launch up to nearly half a billion dollars, so far in excess of actual expenses as to be ludicrous, and effectively affordable only by the US government. When SpaceX got permission to launch their first Falcon 1 rocket from Vandenberg, ULA intentionally delayed the launch of a Titan IV they had on a nearby pad for more than a year, trying to starve SpaceX out. Elon Musk figured it out, took down his rocket, stuffed it into an airplane, and flew it to the Kwajalein Atoll in the South Pacific to use the launch range there, which was too small for Titans and mostly ignored by ULA, and so safe from their machinations. To that point, Elon Musk had spent $90 million of his own money and $0 of any government money to develop the rocket.
The first Falcon launches were paid for by DARPA under a program to test new entrants into the market, but they paid only for the launches, not for the development of the rocket. And again, that program was never supposed to be used. ULA didn't qualify for it and knew that no one was going to challenge them in an extremely tightly regulated and capital intensive market. They let that program be created so they would have something to point to when people like me accused them of being an illegal monopoly. No one was ever supposed to use that money. Their cronies in government had assured them that no one could. When someone actually did, ULA panicked and tipped their hand, rushing to their cronies in the US Air Force, who agreed to sign an $11 billion sole source contract in 2014 in order to lock SpaceX out of the most lucrative parts of the government market. SpaceX filed suit in court, challenging the contract's legality. Justice Department cronies of ULA filed for dismissal. Turns out the judge was not a ULA crony, and denied the motion for dismissal. Air Force cronies of ULA then said SpaceX isn't qualified because they haven't been certified for national security launches. Guess who certifies for national security launches? ULA cronies in the US Air Force, who sat on SpaceX's certification paperwork for six months, before finally proceeding with and certifying SpaceX.
Elon Musk is not a crony capitalist. Elon Musk has been going up against crony capitalists in everything he does, and beating them at their own game.
