From my personal experience, there is a large overlap between people who like to play PC games and people who are interested in and curious about computing technology, and would otherwise be inclined to use Linux. Although the trend appears to be changing with the likes of Proton, the lack of Linux compatibility for games keeps these people tied to Windows, and keeps them from adopting Linux.
