Honestly, Zuckerberg is smart enough to stay out of the way and let people smarter and more qualified to run the show. (This shouldn’t be considered praise. It’s literally the same level of getting out of the way when the fire department arrives to put out the fire.)
Musk is busy publically undercutting his employees (including his recently installed CEO) and fucking things up, and then blaming some jargon word salad.
There are pros and cons to each of them. Musk has mishandled many things during his take over of Twitter, and Zuckerberg has a better temperament as a person seemingly but he also has been running Meta into the ground.
