It's not just AJAX library snippets in ASP.NET, now Microsoft is also including an MPI library with a BSD license with their compute server product. Rampant communism! This software not only has a communist license but turns entire armies of machines into hard working slaves!
(lest we forget: There's also the use of Lucene.NET in Lookout - but that was more of an accident)
(oh, and FTP - BSD licenses all - so nothing sinister going on, just a nice counterpoint to the insane rhetoric against open source)
