I think that nothing pure exists in capitalism. And even when microsoft indeed have that strategy in several ocations, recently the most of the time they truly put money, time and people into the linux kernel development. I'm a free software user too, don't get me wrong, I just don't know a mid size or big project (like apache, gnome, kde, the linux kernel) that doesn't have strong support from the jerks. The tale of the independent developers who work driven by a philosophy is really nice, but is nothing but a tale, all the software is in a way or another related to the jerks, most of cases it is only possible because of the jerk's money.
