Many people use the BSDs for their transparency and despite Linux catching up in many areas, BSDs (which are arguably more political) have a rock solid reputation. (Maybe that's why all of Apple's flagship products are based on BSD - never heard of them using Linux though) IMHO people forget that software development is of course about the tech but really half of the work is about people, both in Opensource and Commercial developments. Large orgs think twice before they use a (perhaps free) software with bad reputation
