The main issue is that a lot of people I know need things like Photoshop or propriety CAD apps or video editing software where the alternatives are simply not acceptable - sure I can mention some OSS alternatives but it's not really my field; this is their job and they can't really take the velocity hit, or waste time finding out mid-project that it can't do what they need it to do.
