"This equation shows that the amount of energy lost in the material in one cycle of the applied field is proportional to the area inside the hysteresis loop. Since the energy lost in each cycle is constant, hysteresis power losses increase proportionally with frequency.[11] The final equation for the hysteresis power loss is[12]"

That agrees with what I said. Yes of course in a typical scenario you'd evaluate frequency in the context of a chosen inductor/transformer in which case frequency also impacts magnetizing current. But if that's held constant hyteretic losses are linear with respect to frequency.
Yes speed of light is a time constant...not one that matters for our discussion.
