I always understood it as RGB being additive -- each color directly stimulates a given color cone in the eye. Whereas process colors (CMYK) are subtractive, because they are a tint. White light hits the paper, but each color (Cyan, Magenta, or Yellow) takes out a certain RGB color leaving the remaining two colors to reflect off the paper. For example, Cyan is a filter for Red, leaving Green and Blue to reflect.

Computer screens blend additively because you emit a mix of light waves; pigments blend substractively because they are filtering out wavelengths from incoming white light. Color spaces and "primary colors" are orthogonal to that.
