They're certainly funding Silverlight for Eclipse.
Very vague reference to funding, and its a self proclaimed reference to funding, but interesting nonetheless.
For the record a contribution in the context of support for interop (which is the reference links in the guts of the blog post you linked to) Microsoft would support most any 3rd party sponsored initiative. It's a bit of stretch to make the statement microsoft
is funding this or that, one automatically thinks that the funder is pushing this or that technology through to market. That's not the case here as I see it. Thats not to say that an effort isn't underway either. One may very well be, but this post nor any
of its references speak to that.
