The steam deck being based on arch probably influences it a lot too. You can see the same trend on the steam hardware survey results.

edit : My bad actually, the video creator mentions in the comments that this is data without the steam deck section of the site.

Aye much appreciated, will look at it later when I got some free time.

I'm starting to consider watching it because it's about half of what I see here lol

Edit : I am enjoying TOS so far, not very far in though.
