TL-DR: Push GutHub Enterprise sales through existing Microsoft sales channels, and push Azure and related products to GitHub users.
The first doesn't matter to me. The second makes me think everything from "Add a .azure.ci.cfg file to your GitHub project to trigger builds, only $X/metric!" (not so bad) to "Advanced issue management available through MS Project 365 integration, please ask your project admin to subscribe to Office 365 to unlock!" (please, no...)
A large part of GitHub's appeal to the open source community was that all features were available for free to open source projects. If Microsoft wanted to make more features available for free to open-source projects, then Visual Studio Team Services would be a much, much different product, and Microsoft wouldn't need to acquire a platform that directly competes with their current product line.
