(Of course, there are also large chunks for which Red Hat employees write as much code as anyone; but certainly that's not true for every package.) I think the real criterion for big companies is not so much whether you're supporting your "own" product as whether you're big enough to be worth suing if things go wrong. regards, tom lane
