Most of these republicans/libertarians only want the government to leave them alone. They don't care when a company they aren't affiliated with is regulated. You can see Marc Andreesen celebrating the government's decision on Anthropic. Similarly, when Silicon Valley Bank went bankrupt, libertarians such as David Sacks were loudly calling for government bailouts. It's just hypocrisy all the way up.
The label of libertarian is thought of as a binary by non-libertarians, leading to this perception of hypocrisy, but that is not the way actual libertarians think with the exception of a tiny minority. Libertarianism is a spectrum, just as any other political affiliation or belief system.
This idea that if some group isn’t all reading from the same sheet of music you imagine they should be reading from means they are hypocrites is just wrong.

The entire movement of conservatism in America is a propaganda operation oriented around manufacturing consent for a return to the Gilded Age. It is entirely bankrupt of morals and has been from the beginning. If you personally are a conservative, now is a good time to take a good hard honest look at the history of your movement in American politics. There might even still be time to realign yourself with a movement that isn't actively seeking to harm you.
