I thought the Linux gaming pc challenge was fair. You have to remember that most users are not technical at all and that’s where Linux falls down.
The only thing I disagreed with him majorly on was his complaint about the GitHub interface not downloading files you click on by default. I get where he’s coming from as a non-dev, it’s jarring and confusing but as a developer that’s the last thing you’d want. His complaint about GitHub’s interface really should have been directed at all those people using GitHub as a place to store files. But that’s so intrinsic to Linux, it’s hard to get away from yet it’s something that does prevent Linux from appealing to the mainstream.
Don’t get me started on the reliance upon the terminal and bash scripts to achieve anything. I cringe every time someone says “just go here and copy/paste these commands”, not just because it’s unintuitive but because it’s also a major security risk. Not that windows is innocent of this either but it’s much more common in Linux.
