I'm not sure that's true. I get the impression that he acquired Twitter for political reasons. And all of Musk's associates egging him on were right-wing political activists. An extreme example of this is Larry Ellison, a well-known funder of right-wing causes. It came out in the acquisition trial that Ellison offered Musk essentially a blank check to invest in acquiring Twitter. Yet at that point, Ellison himself had only ever tweeted once, back in 2012. He doesn't give a crap about Twitter or the Twitter experience, except insofar as it advances his political cause.
(Just checking, I was surprised to discover that https://twitter.com/larryellison/with_replies tweeted twice on October 5, thereby tripling his all-time tweet count from one to three.)
Musk himself has said things like, "The woke mind virus is either defeated or nothing else matters". Whether he's serious or not, who knows, but we can't assume that $billions in losses necessarily matter to someone of Musk's extreme world-historical wealth.
