Elon stopped being a liberal fan favorite the moment he agreed to be on Trump's whole climate committee crap early on.

If you were to use any search engine and search "Elon Musk out of touch" you should see any number of leftist outlets saying basically the same shit.

Also, Elon has earned a lot of money through non-taxpayer ventures. It's not just through taxpayer money.

Finally, if you have a problem with the tax system and how that money is spent, do your utmost to stop it at its source instead of the people who receive the money.

Taxation is theft to begin with. You don't go after the merchant who sold their goods or services to the buyer who stole the cash they're paying with; you go after the person who stole the money. In this case, the government.
