I have a feeling that Twitter could be politically important enough to have one or more governments reign them in unless Musk manages to calm things down or drive it into the ground.
The smartest thing he could do is find some pretext to remove his public persona from the daily operations. He's clearly in over his head (micro managing policy etc) and business sense alone should tell him that.
Twitter is hard enough technically, but the global compliance/regulatory challenges must be daunting.
