Not just in education, but even at work, companies or even governments would rather have MS, for example, paying them hefty contracts, while hiring borderline minimum wage workers to run such systems. I remember I had similar arguments with an executive before, and I recommended hiring competent people and using alternative tools. The answer was simple: "We don't want to have XYZ department relying on this person/group, but rather on this big popular company." They thought they were mitigating the risk, only to put all their eggs in one basket!
