Elon Musk – the world’s richest person – recently announced that he was pulling out of his agreement to buy Twitter, saying that there was a lack of information about the number of Twitter users made up by bots. In a letter sent to Twitter, Musk said that Twitter was "in material breach of multiple provisions" of the original agreement. The resulting back and forth could end up in court, but many predict it will end with a (quiet) negotiated settlement.
