(With apologies, this started as a 'damn Microsoft...' rant, and turned into a bit of an anti-DRM sermon)

In light of some recent news (Microsoft is essentially killing OpenGL, either 'cause it's too hard to implement or because they didn't invent it...) I was thinking back about Microsoft's history, and I was wondering... Why does anyone with a brain or a sense of self-preservation support them, or any other company that seeks to lock us in?
