Nor in NeXT, but it shows a history of Unix/FreeBSD development at Apple prior to the hire of Hubbard during the Mac OS X era. That is to say, his status as co-founder of FreeBSD and Apple hiring him wasn't merely a coincidence.
And to clarify my example, Fuchsia is set to be a Linux-less functional rebuild of Android, but it'd be a bit myopic to point out that "there's no Linux in Fuchsia". It's like saying there's no Steve Jobs in any Apple products created after his death. Less perhaps, but not none.
It won't be that many years before I imagine we'll start seeing people asking to cite how the next forms of ChromeOS or Android were related to Linux.
