Ah come on! It's more complicated than that. Most of the heavy lifting in OmniSharp is done by Roslyn [0]. Roslyn is the open source C# compiler and code analysis library maintained by MS. You cannot overstate how much effort has gone into Roslyn, and how much money MS has invested to make it work. OmniSharp is essentially a wrapper[1] around Roslyn (before Roslyn it was Mono), and while the OmniSharp team did a nice job developing a nice intellisense UX around it all, it is not like MS is taking it all away from them. Incidentally, it is almost certain that new intellisense plugin by MS will also be built on top of Roslyn.
