Elon Musk has been trying for months to make Twitter a profitable company, but he’s had a lot of ups and downs along the way. He’s made fundamental changes to the platform (hello $8 check marks), fired thousands of employees, proposed an ad revenue sharing program for Twitter users, and even restructured the algorithm to get more impressions on his tweets. In interviews, Musk has been clear that his mission is to “save Twitter,” even if he’s broken things at the company along the way.
