I generally want to avoid telling people to copy and paste commands they dont understand, especially things like one line installs. I understand what you mean, and while you and I know there is no risk to using RPMFusion, a windows user should never be underestimated in their ability to screw Something up. (See: Linus Sebastian installing Pop!_OS) and most new users do not want to interact with the terminal at all. I feel like if we want people to start using Linux as a daily driver, the option to never use the terminal should be available to them.
