Microsoft to bastardise RSS

Dave Winer has a “sneak peek” at what Microsoft are about to announce on the RSS front. But his post includes the awful line:

I want them to relax and give a really great demo on Friday, and know that the OPML Editor will support the very simple extensions to RSS that they are developing, and I look forward to collaborating on further extensions and perhaps even new formats as we go forward.

Now, I know that RSS can be extended – it’s part of the spec. But the cynic in me wonders whether Microsoft’s extensions might be produced in their “self-interest” – and of course they’ll push them to become standard RSS markup.
