Microsoft eventually admitted that it was wrong about open source, with Chairman Brad Smith saying that "Microsoft was on the wrong side of history when open source exploded at the turn of the century." Microsoft's opposition to open source software, and Linux in particular, was at times extreme and nasty, with former CEO Steve Ballmer declaring that Linux was "a cancer that clings in the intellectual property sense to everything it touches" in 2001. Given the company's antipathy, which was based largely on its fear that the free and open source Linux operating system would eat into Windows' market share, it's all the more remarkable to see how much Microsoft has embraced open source recently. and is now, in fact, the world's largest contributor to open source projects. The company has released a number of open source tools, such as Visual Studio Code, and many of us were looking for flying pigs when it was revealed that Microsoft would actually be shipping the full Linux kernel to Windows. 10 as part of the Windows Subsystem for Linux (WSL) functionality. Meanwhile, Linux distributions like Ubuntu are available for download from the Microsoft Store on Windows 10.
