Funny of you to say that. I've got a Orange pi 5 MAX (which I'm pretty sure it can fall into the "not a easy machine to install Linux" category) and the experience, for the most part, was straightforward. (You've mentioned an issue regarding mices --I've got a "Ragnok 2 gun mice" and it "just werked" on it. No tweaks or "mental gymnastics" required.). Hell, even enabling hardware acceleration was very straightforward as is -- you just have to know where and what to look for.

I'm not trying to defend Pewdiepie -- just saying that Linux can be "user friendly" just like Windows if you know what you are dong.
