He blocked a US funded military strike that would have sunk Russia’s navy a while back.
(The definition of treason in the US is extremely clear, and he obviously crossed the line.)
The story as popularly told was simply inaccurate. I suggest you do some more research.

If New Glenn works, with first stage reusability, then Blue Origin could be a few years behind in launching Kuiper as a Starlink competitor. Outside of what's going on in China, Blue Origin is probably the most likely to succeed in competing with SpaceX.
Don't get me wrong, I like RocketLab. But going against SpaceX will be a long race requiring deep pockets that can fund years of unprofitable development.
Musk does not have any incentive to help you and me, he has an incentive to use the government apparatuses to further his businesses. He is a good businessman who has made two very valuable companies; this does not mean he will use the government responsibly, e.g. by ensuring fair competition. As a simple example, after having relied on it for years, he is now trying to eliminate the EV tax credit because it will harm his competitors more than him [1]. This kind of regulatory capture is not good, and we should not cede government power to him or people with conflicts of interest like him.
