What is he thinking? Putting this person in charge, with her ties to the global censorship-obsessed WEF, seems contrary to Elon's mission to make Twitter a place for free speech.
My best guess is that he wants to raze it to the ground and salt the earth on which it once stood so that nothing can grow there again. Not just destroy it, but destroy it so thoroughly and comprehensively that it cannot be rebuilt.
I mean you could apply "What is he thinking?" to almost anything he's done with Twitter. Which leads you to the obvious conclusion... he does not think.
