No. He's said it's not usable by your average gamer, which is different. And for him personally it definitely has pain-points as it's unfamiliar, as the linux challenge showed.
He sings it praises on the SteamDeck, because valve has given SteamOS a UI that anyone can figure out by just using it.
Same for ChromeOS, he knows that windows needs to fuck off, but he's also closer to the average person in terms of how much he needs an OS to hold his hand and stop him from breaking things (again, linux challenge).
The problem I have with his "challenge" is the same problem I have with all so called Linux challenge type videos. The average user is not installing an OS, any OS, period. Judging Linux by how an average user can or cannot install it is disingenuous and stupid. It should be judged on how usable it is by the average user if it's already installed and setup because that would be how it's used. It would be installed by someone that knows what they are doing just like they do with Windows.
There are companies that do prebuilt PCs around here. Heck, the prebuilt thing doesn't usually cost anything, you just point out the components you like and you get charged just for them, while getting the full assembled PC from them. Most of them will even allow you to give them components not purchased from said company, to put in the build. Even old (used) components.
I have the exact opposite opinion. He’s exactly the person that the Linux fanboys are pushing to adopt the OS, Tech Savvy, but not with sysadmin levels of knowledge.
The average user is going to have to install linux if they want to use it. It’s not going to ever come as the default option as long as Windows and Max exist. So an average user is going to have to install, and then configure the OS. That’s going to be a universal pain point in adoption.
Windows computers don’t come pre setup with software (for the most part, there’s some small exceptions for pre-built manufacturer software bloat), neither should any linux install. A user is going to have to understand how to install and configure the OS as that’s an integral part of running it.
