I am quite disappointed. Given the title, I was like, wow, a generalist PC gaming website recommending people to switch to Linux! Read the article, Linux is not mentioned at all, I don't even know why it is in the title. Getting a few clicks from hippies?
I don't think it's making a serious suggestion. It's using "learn Linux" as an ironic punchline, like "just move to Canada". It's a kind of backhand.
This guy has seemingly never written about Linux before. No other articles mention it that I can find, except one where he talks about Linux overtaking Apple in gaming, where he talks mostly about Apple.
