Important Point the Submitter Omitted (Score 5, Insightful)

Free (as in libre) software is not mutually exclusive with capitalism. Ask RedHat. Or IBM. Or any number of companies that develop free (again, libre) software and make a profit (or, at least get a return in dollars) while operating in a capitalist system. The opponent here isn't capitalism. It's closed software and closed development methods. Of course the US (and a number of other countries, I assume) wants to promote capitalism. But it can do that and also promote free software.
