This strikes me as a probably outdated view. If anything, Microsoft has de-emphasized preinstalled games and canned most of them since Windows 8, relegating them to being optional installs from the store. The internet says that the only preinstalled game in Win10/11 is Microsoft Solitaire Collection - but I can't even find that on my Windows 11 Pro install. So, considering macOS Chess, it's a one-for-one in terms of preinstalled games.
