There is no way I can see them open sourcing GitHub. If you have studied the history of versioning control systems (ClearCear, Perforce, TFS, Subversion, etc.) you would know how insanely powerful controlling the hosting solution is. I can see Microsoft making private repos for free and/or making GitHub Enterprise free for the first 10 users though.

It's definitely powerful, but I don't think the power of github is in the actual product. Gitlab is much better in some important ways (IMHO of course), but it's still not seen much adoption. The power of Github is in the community and the fact that it's the defacto standard place to look for code. That would likely only increase if MS open sourced the code.
