Phrasing

The Verge with a headline “Fortnite keeps stealing dances – and no ones knows if it’s illegal.” If no one knows, is that stealing? Seems like the sentence is missing a modifier. Or perhaps it should say that the publisher believes this is stealing. Or… isn’t this sort of like saying light travels at 299,792,458 m/s – but no one knows what light is. That sentence provides no information. Thanks, Verge.
