After getting EU approval a week ago, today Microsoft’s acquisition of GitHub, the Git-based code sharing and collaboration service with 31 million developers, has officially closed. The Redmond, WA-based software behemoth first said it would acquire GitHub for $7.5 billion in stock in June of this year, and after the acquisition closed it would continue to run it as an independent platform and business.

The acquisition is yet another sign of how Microsoft has been doubling down on courting developers and presenting itself as a neutral partner to help them with their projects.

That is because, despite its own very profitable proprietary software business, Microsoft also has a number of other businesses — for example, Azure, which competes with AWS and Google Cloud — that rely heavily on it being unbiased towards one platform or another. And GitHub, Microsoft hopes, will be another signal to the community of that position.

In that regard, it will be an interesting credibility test for the companies.

As previously announced, Nat Friedman, who had been the CEO of Xamarin (another developer-focused startup acquired by Microsoft, in 2016), will be CEO of the company, while GitHub founder and former CEO Chris Wanstrath will become a Microsoft technical fellow to work on strategic software initiatives. (Wanstrath had come back to his CEO role after his co-founder Tom Preston-Werner resigned following a harassment investigation in 2014.)

Friedman, in a short note, said that he will be taking over on Monday, and he also repeated what Microsoft said at the time of the deal: GitHub will be run as an independent platform and business.

This is a key point because there has been a lot of developer backlash over the deal, with many asking if GitHub would become partial or focused more around Microsoft-based projects or products.

“We will always support developers in their choice of any language, license, tool, platform, or cloud,” he writes, noting that there will be more tools to come. “We will continue to build tasteful, snappy, polished tools that developers love,” he added.

One of those, he noted, will be further development and investment in Paper Cuts, a project it launched in August that it hopes will help address some of the gripes that its developer-users might have with how GitHub works that the company itself hadn’t been planning to address in bigger product upgrades. The idea here is that GitHub can either help find workarounds, or this will become a feedback forum of its own to help figure out what it should be upgrading next on the site.

Of course, the need to remain neutral is not just to keep hold of its 31 million developers (up by 3 million since the deal was first announced), but to keep them from jumping to GitHub competitors, which include GitLab and Bitbucket.
