Reasons for MS to start a few OS projects (Score 1)

From the company's perspective the most appealing thing about open source programming is that they don't have to pay all the programmers. Device drivers seem a good place for Microsoft to start open source projects. Maybe they could open the source software projects which they may have killed. I don't think anybody at MS will argue with the point that the more code that is written for an OS, the more useful the it will be.

This being said, you can't ask them to stop selling software. You can suggust that there are some places where they could lower their costs by allowing the community to help.
