I think we should dump the "fictitious force" and "pseduo force" nonsense and say what we mean: "frame-dependent force", as in this force depends on the observer being in a specific, non-inertial frame of reference. These forces are real, and observable, and their existence distinguishes inertial from non-inertial frames, which is a useful thing to do.
