It's because it's what we're used to. I have used a Mac a whole entire 10 minutes my whole life. And those 10 minutes I could not figure out how to do anything. How to search. How to open apps. How to print. How to connect to WiFi. It's all so incredibly hard 🤣
Key commands are good to know in Mac. Cmd-Space search anything and open apps, Cmd-tab switch between apps. In the Finder (desktop) the file system is pretty simple. Open drive, you have Applications, Library, System, Users with home folders, very Linux like actually
