It is true about Windows OS. Just in the gaming industry, games are made on Engines that run almost entirely on Windows. Linux certainly comes in as well, but I wouldn't be surprised if it's 90% or more on Windows. That includes games on Nintendo and PlayStation consoles. Steam, Epic Games Store, Origin, etc. would not exist if it wasn't for Windows. And Steam is even considered the monopoly on PC gaming storefronts lol.
MS provided the tools that allowed the gaming industry to rise as much as it did. Competitors like Apple were minimal to nonexistent because that just wasn't the target business.
