VSTS does a lot of things that GitHub does not. VSTS takes the workflow roles of Jenkins, GitHub, Jira, and has a few additional features that I don't know what open-source equivilant exists for (staged production, push to cloud - maybe done as Jenkins plugins?). It's highly unlikely VSTS will be shut down, especially in favor of a project which does very few things that VSTS does.
