Historically, Microsoft has been a software company primarily centered on selling proprietary, closed-source software. However, in recent years, it has been transitioning towards open source. The acquisition of GitHub, the world's largest source code hosting platform with over 40 million users, aligns perfectly with this shift. This move positions Microsoft at the core of the open-source development community. Additionally, it enables them to more closely integrate their existing services and tools, such as Visual Studio and Azure, with GitHub, potentially drawing those millions of developers to their platform and technologies.
