How much GNU is there in GNU/Linux?

a) I said *I* will continue to name it GNU/Linux. You can do whatever you want, and I wont fire a shotgun at you. However, if asked, I will continue to motivate it in the same way.

b) nobody forces a name on Linux, except maybe Android people. The kernel still is named Linux. It's the whole system that's named differently. If one is to follow your "don't force names on things logic" you can't name your system Debian, Fedora, SuSE, Gentoo or Ubuntu, for that matters. By the way, I am free to call it Bonkers OS, if I like, since there is no trademarked name for the whole combination as an holistic system.

c) I am also interacting with Windows computers, indirectly. I do not go so far as to say I am using a Microsoft Windows system just because of that. I find *your* comment rather naive.

d) With my software engineer hat on: LoC *is* a poor metric, they not only discourage you to use that at school (at the university they fail you outright if you try to use that directly to estimate effort) and at work (Bill Gates is credited to criticize the IBM effort-estimation mode based on SLoC by saying: "Measuring programming progress by lines of code is like measuring aircraft building progress by weight."), but commons sense should help you too to understand it. Numbers will not help you when you use the wrong method to measure the wrong thing.

I do not have to show that the numbers themselves are wrong, as you suggest. Running the experiment again would be pointless, because its based on a wrong set of hypothesis.

I am claiming that this report shows nothing of interest to support your denigrating notion about the GNU project, to which you seem to have a personal grudge against.

LoC was introduced as a metric around 1960. Not only agreeing about what SLoC means is difficult, it also is hard to adjust that value for different languages and programming paradigms.

Look: two SLoC:

--------------------------

#include <iostream>
int main () { std::cout << "Hello world!" << std::endl; }

--------------------------

Look: more SLoC:

--------------------------

#include <iostream>

int
main ()
{
using namespace std;
cout << "Hello world!"
<< endl;
return 0;
}

--------------------------

I advise reading the following book: N. E. Fenton, S. L. Pfleeger, "Software Metrics: a rigorous & practical approach", PWS Publishing 1998
