There's also minimal ethical/moral hazard associated with the projects cited. Pharma trials mean that some nonzero proportion of the study populations will subjected to side effects, some of which may be permanent and debilitating. Some study participants may even die as the result of an adverse event. This is a major disincentive to development that the opensource projects cited never have to face.
