Does Open Source Software Cost Jobs?

jfruhlinger writes "John Spencer, a British blogger and tech educator, is convinced that free and open source software, which he's promoted for years, is costing IT jobs, as UK schools cut support staff no longer needed. But does the argument really hold up? It turns out that the services he's focused on are actually cloud services that are reducing the need for schools to provide their own tech infrastructure. Of couse, it's also true that many of those cloud services are themselves based on open source tech."
