I read the article... and it says that the largest single source of code when it was written was FreeBSD. 21MM lines out of 39MM overall.

Now since then they've released a lot of new features and what-not so I doubt it still holds at 53.8% but I would bet it is still the single largest source of code.

Does it matter? No.

Thank you.
