Compare and contrast the culture at twitter before October 27, and after Elon Musk took over.

employees and began making drastic changes to Twitter's corporate culture. In an article for Insider.com published on November 4, 2022, an anonymous Twitter employee described the shift in Twitter's culture like this: "One of Twitter's core values was transparency. All of our calendars were open. You could look at our former head of engineering's calendar and see where he was having lunch that day. Documents were usually open and viewable. With a project, you could see who initiated the work, who was the assignee, who was in the chain of command. That's all gone now. I can't find the information that I need to see about the projects that I'm working on. Documents are locked. Permissions are closed. I'll click on a project that I'm supposed to help with and find out that I'm blocked from seeing it. Before Elon Musk took over on Oct. 27, that would have been very unusual. I did not come to Twitter for the money. I joined because I cared about the mission, which was to serve the public conversation. The people who work here really used to care about the product. The employees could have easily gone elsewhere and made more money. But they stayed because they believed in the mission, and they did their best. Up until the sale, there was genuine transparency. People at the bottom knew what was happening at the top. You could go in and read about anything that anyone in the company was working on at any point in time. There was a staff hierarchy to be sure, but the culture was quite democratic. Now, people outside the company know more about what's happening at Twitter than we do. As of this week, our senior leadership is gone. The heads of engineering, product, and revenue have all been fired. Elon has brought in his men from Boring Company and Tesla to run the show. I'm concerned that the next generation of people building Twitter won't believe in the core of our mission. They'll believe in Elon Musk. Twitter shouldn't be a for-profit company. One person shouldn't have the power to set the limits and the tone of the public conversation. It's been such a strange transition. I keep on working as if nothing has changed. The one difference is that people are staying much, much later than normal. These are mostly engineers. They worked around the clock to deliver all of the features Elon wanted. They've been there ever since, working entire weekends, and sleeping there. I've heard stories of people being asked to work literally around the clock. Engineers are being weekend and then being called and asked to do things immediately
