You may be out of touch with people that are used to GUI. For example, during the first installation of linux distro after the user is landed on their DE, as far as I know, no distro ever curates the terminal to them. Like "this is the menu", "this is the terminal emulator", and even after the user managed to open the terminal, it is not obvious what to do next as there is only text prompt. Remember, users using GUI usually encounter text prompts with some hint (username, comment, email). Meanwhile the terminal has nothing. Suddenly you see the user you are logged in as and a blinking cursor. After that, how do you know what apps are installed? What commands can you call? Typing help doesn't always help on every distro. Again, remember, users using GUI will see what apps are installed usually using a menu of some sort. There is a lot of friction coming from GUI if you have never encountered CLI before. Heck, I bet some people have never installed an application outside from an app store or their commissioned device. Even a file explorer concept is foreign to some.
