> Microsoft claims that they have developed a "standard" called .net, so it's their responsibility to maintain the ecosystem in a manner that makes .net code portable.

I think it's fair to add if they want to. It's surely up to them whether they wish to support .Net on other platforms or not.

In fact that matches typical FOSS project workings; where a piece of software is usually put together for a particular platform and then a third party (or sub project) takes on the porting/cross compiling.
