@drq one reason I can think of is newcomers being *scared* of said box, after being conditioned by numerous jokes (some of them pretty cruel) about the destructive commands.
And command naming doesn't help, making most commands look like arcane language of random letters mashed together (Pacman being probably the worst offenders among package managers in particular) and not even readable *aliases* available by default. It's ergonomic for day-to-day manual use to someone already familiar with it all, but approachability suffers as a result.
And don't get me started on VT-100 still holding on to dear life of ruining the consistency of textual inputs between itself and the rest of GUIs. Like, copying actually *interrupts* ongoing work? Right-click is *paste*? «Dafuq?»
