There's a simple test for this - compare how many times Elon has been wrong or outright lied on Twitter vs how many retractions Axios has had over the years due to bad sourcing.

Off-handedly, I've never seen Axios accuse a cave diver of pedophilia or back out of ending world hunger but my perspective is limited. I also assume Axios has a lot of fact-checking processes before they put something on the internet when compared to a tech CEO posting on his own platform. But you may have done a deeper dive on this with a truly rationalist, epistemically rigorous framework.

Musk and Trump have a long track record of lying, Axios doesn't.
