But it's still a good point that the article presents itself as a response to claims such as the one quoted:
Open-source, volunteer-created computer software like the Linux operating system and the Firefox Web browser ...which almost certainly refer to the whole Linux operating system package, with the GNU stuff, Xorg, KDE, etc., etc.
Numbers for the Linux kernel certainly help to answer the question posed, but it's worth at least pointing out that the kernel is probably one of the less representative samples one could make of the operating system.
