RSS in the browser and OS?

I was just reading the link from Dave Winer’s post “Microsoft will not swallow RSS any more than they swallowed hard…”

In the linked article from PC Magazine, Lance Ulanoff compares support in Longhorn for RSS to Microsoft including utilities in past OS’s were 3rd parties were put out of business. Now RSS in the OS is something new and is intriguing. But he also mentions

“IE 7 will launch later this year, and Longhorn will finally arrive in 2006(?), both sporting easy-to-use, seamlessly integrated RSS capabilities.”

Other browsers already sport integrated RSS readers, is he saying that integrating an RSS reader into IE is a bad thing and Microsoft will put companies out of business?

Confused.
