Betteridge's Law applies.

Gaming helped cement DOS/Windows victory on the desktop because most enthusiasts bought computers to play games, but it did nothing for the Amiga (which was great for gaming but had a lousy ecosystem for office stuff).

On the other hand, the desktop market is collapsing and you might think that the kind of person who still wants/needs a desktop might be more likely to be the kind of person who wants/needs Linux. That's possible but it's not the perspective taken by the article.
