The articles about Microsoft employees rooting around in Haiti were probably intended to burn up any quota about IT in Haiti so that no more is said about FOSS helping.
The latter example features OpenMRS which is a big name along with the VA's VistA. It's worth noting that Windows Vista is probably an attempt a 'google-jamming' the name of VistA, just like MSOOXML appears to be an attempt at 'google-jamming' the project OpenOffice.org.

The software was never intended to work, it was intended to sell Microsoft products to naive or uninformed medical staff.
