About this piece
Evidence: the only numerical claim is the study count. Höffler and Leutner (2007) reviewed 26 primary studies and found a medium-sized overall learning advantage for instructional animation over static pictures (d = 0.37). That result is about learning in instructional settings.
Editorial metaphors: the frozen jumble, the A-to-B morph, the lightbulb, the eye tracking a moving orb, the gears, and the four use-case scenes are illustrations. They are not data, and they do not claim that every animation lifts engagement or sales.
