Linux kernel development has been coordinated via mailing lists for ages. Linus wrote the git version control system specifically to suit the development of Linux. GitHub made git mainstream, and they made lots of great features for the masses. But there is no reason for the Linux project to change the way that they like to work just because of that. Still, a copy of the Linux source tree is also hosted on GitHub. So it seems to me that everyone gets what they want. Linux get to continue their development in the way that they like to do it. People on GitHub can easily find the copy of Linux on GH, and browse the sources there. And they can create forks of the Linux sources on GH too.
