I think a lot of the Mono Team worked for Xamarin. As Microsoft acquired Xamarin and by that act, opened up most of the Xamarin/Mono codebase that had previously been licensed to ensure a commercial fee could be generated.
Miguel posted the article and he's a Microsoft Employee for sure.
I think the runtimes are slowly converging. The main issue at the moment is that Core is more focused on Web and back-end targets. To replace Mono, it needs to support UI targets such as desktop Windows, Mac and Linux, as well as mobile targets such as Android and iOS. It'll happen. Most of the .Net platforms seem to use the Roslyn compilers these days. Next step is to converge at a library level, then at a VM level I think.
