He blew up a starship test because he overrode engineers, thought he knew better than them, and didn't install a blast deflector under the rocket. It made a giant hole in the launch pad and the concrete debris damaged the rocket.
I thought the Starlink thing mostly took place before he purchased Twitter, no? The harassment case predates his purchase of Twitter as well, but it looks like it's still an issue presently according to your article. I haven't heard much about this in a while, it fell off my radar. Thanks.
