I've never quite forgotten that Ballmer accused anyone involved in Open Source as Communinists. Not to mention he said that Linux was a "cancer".
Or to be precise, he said that:
"[W]e have a problem ... when the government funds open-source work. Government funding should be for work that is available to everybody. Open source is not available to commercial companies. The way the license is written, if you use any open-source software, you have to make the rest of your software open source. If the government wants to put something in the public domain, it should. Linux is not in the public domain. Linux is a cancer that attaches itself in an intellectual property sense to everything it touches. That's the way that the license works."
and of Linux and Communism:
"There's no company called Linux, there's barely a Linux road map. Yet Linux sort of springs organically from the earth. And it had, you know, the characteristics of communism that people love so very, very much about it. That is, it's free."
