Linus Torvalds with Linus Sebastian (Linus Tech Tips)

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I mean, I feel like he outright confirms it in the video. It's his distro of choice since it allows him to easily use his own compiled kernels in testing. Anything else is an inconvenience to his work.
Ah, but primary recountings aren't sources, you first need to write an article or book about it (according to Wikipedia sometimes)
Interviews do typically count, it just has to be citable. Videos are sufficient in that regard as well, not just articles or books. It would be different if Torvalds had edited his own wikipedia page, but an editor who updates the page and cites this video would not be in the wrong.
