It is irresponsible how incorrect this explanation of physics is. Rotating a magnet does not simply create EM waves. The changing magnetic field from the rotating magnet is not the same oscillating magnetic field induced by a photon.

Photons are not simply ripples that propagate outwards from some disturbance of a field.

Rotating a magnetic does quite simply create EM waves, alongside other electromagnetic field changes. It just doesn’t only create EM waves. There is certainly nothing irresponsible or even really incorrect about their explanation. It’s a bit of a simplification, sure, but that’s appropriate in this context.
