LOL you did nothing of the sort, you claimed several OTHER entities had more copyrights in Linux, but then your very own link showed GNU (which stands for NOT UNIX) had more than all those you mentioned combined. Yet here you are again of course, trying to use the same disproven claim that GNU isn’t relevant to Linux when they own more copyrights than anyone. No surprise, it’s how you operate, as more and more keep finding out.
Yes, by title, not by code as you said. GNU includes a LOT of small junk titles that are of little interest to anyone but a very few. These are generally not installed by default in Linux distros, usually not on the CD, mostly available through the online package management tools. So even if you count them, it's still by title (as I said) not by code (as you said initially).
You're so dense you can't even realize that you've learned something.
