It has been rumored for years that Microsoft might acquire Ubuntu. This is an interesting move though not proof of any such future merger. All of that said, it would be nice if Microsoft had the same level of cooperation with Fedora and another distro or two as well.

(And where the hell is support for .NET Core on FreeBSD???)

I've always thought that a Microsoft Linux distribution would be incredibly interesting. They could give the user experience a new round of polish without being weighed down by the years of legacy support, compatibility, and cruft on Windows.
