Musk might do it because he knows the game is over and he's won. It doesn't really matter it Stewart makes Musk look like shit. Facts don't matter and Elon Musk is the shadow president.
Like when he went on JRE and had that whole stupid debacle with him being an "expert POE2 player", then he streamed himself having barely any idea how the game worked. Because it didn't matter that Musk was just lying - what are you gonna do about it?
