What's behind the fight between Elon Musk's X and Australia's eSafety commissioner?

Elon Musk is at war with Australia — in particular Australia's online safety regulator — due to videos that were circulating on his platform after an alleged stabbing at a church in Sydney last week. After the eSafety commissioner requested all social media platforms to remove video of the stabbing from their platforms, X made the videos unavailable to view within Australia, but they're still available to watch both outside of Australia. Now, X and the eSafety commissioner are fighting it out in court, while X's owner Elon Musk continues to fight it out online. Guardian Australia's Josh Taylor explains what's going on behind the tweets.
