Microsoft’s love for open source software continues as they have now joined the Open Source Initiative (OSI) as a Premium sponsor. OSI is a non-profit that is focused on promoting and protecting open source software through education, collaboration, and infrastructure. Microsoft mentioned that today’s announcement represents one more step in their open source journey.

Over the past few years, Microsoft has increasingly participated in open source projects. Apart from .NET, Microsoft open sourced Visual Studio Code, Microsoft Edge’s JavaScript engine, Xamarin SDKs and PowerShell. The company is also a leading contributor to open source software projects on GitHub. They joined OSI Affiliate Member Linux Foundation and many of its projects. In addition, Microsoft has partnerships with several open source companies like Canonical, Red Hat and SUSE.

“This is a significant milestone for the OSI and the open source software movement more broadly,” said Patrick Masson, OSI General Manager and Board Director. “I don’t think there could be any greater testament to the maturity, viability, interest, and success of open source software than not only Microsoft’s recognition, but also their support as a sponsor, as well as their participation as contributors to so many open source projects and communities.”

“The work that Open Source Initiative does is vital to the evolution and success of open source as a first-class element in the software industry. As Microsoft engages with open source communities more broadly and deeply, we are excited to support the Open Source Initiative’s efforts,” said Jeff McAffer, Director of Microsoft’s Open Source Programs Office.
