I care little for whether someone pedals or not. While someone is not cycling or using their "e-bike" as a bike, it matters little aside from befitting someone's nitpicking. However, if it is to be known as an e-bike, it must be useful as a bicycle. Adequately capable of traversing a typical urban environment on human power alone, in other words.
However, on cerewa's mention of impact and weight, its worth noting that many of these scooter bikes pack 100+lbs more potential than a typical "true" bicycle e-bike does. Thats a whole lot more potential for carnage.
