It's a good thing that stakeholders of MS and open source are finding how they can coexist. In addition to site like Ohloh.net and CodePlex, there are more emerging open source applications for the .NET platform. To avoid IP issues, a BSD license may be preferred by the MS crowd, and is featured in applications such as DotNetNuke and ListRing. The idea that it is MS versus open source as a whole is simply not valid as more for-profit organizations get into the mix. It is simply a matter of finding which approaches to open source fit best.
