The reason why the EU “slapped” Microsoft is instructive though: in a nutshell, the argument was as follows: it is so big that it can crowd out other smaller competitors because it can offer products for almost free (because their marginal cost is basically zero) whereas starting up and/or sustaining a small competitor (perhaps with a subset of functionality, for a lower TCO) is more expensive. Since producers are (as remarked elsewhere) seen as “vehicles for job creation”, this is a net negative.
