It's more subtle than that. The Dutch schoolmaster CIO only has two pieces of software to choose from, one of which is a bunch of outdated Windows desktop apps that are terrible to work with and the one TFA is about, which is a fairly decent set of web apps that unfortunately have never worked on anything but windows (first they used all sorts of ActiveX components, now it's a bunch of Silverlight crap, apparently).
So there really is very little the schoolmaster CIO can do, and given the lack of options, he probably made the best possible choice.
