Notice how the argument breaks down.

It is the case that the open source model has made Linux difficult to compete with (though that is in significant ways the result of commercial development; still, those corporate contributors were coerced into open source development by Linux's success, and would have done things differently in a VxWorks alternate history).

But that same open source model produced Fetchmail. Most startups could produce something comparable to Fetchmail, even if forced to use 1999 tools. The open source model didn't turn Fetchmail into an insurmountably dominant tool in its space; Fetchmail had fallen into irrelevance even before Google Mail made all of these kinds of tools irrelevant.
