You can use Ubuntu/Mint/elementary/etc. and it's very user-friendly. You can pay Purism or system76 to deliver you a literal physical out-of-the-box experience.

But, like, let tinkerers tinker. Nobody said that this should be the way to go for everyone or that user-friendly unix does not exist. You brought the assumption that all Free Software is like that into a thread about a specific less-popular explicitly-not-desktop-oriented OS ;)
