Nobody claimed that they use motors in every single race. Plus, Jonas at this time does not appear to be the most obvious e-biker in the peloton. That honor belongs to the namesake of this thread. So we might as well concentrate on him as the most pure academic case of the phenomenon in question.
You might want to rewatch the performance of the aforementioned namesake from the last year while paying attention to the ease of them and often quite literal lack of sweat. If that's "grey area," how do you believe a "black" one would look like?
P.S. As was noted in this thread a bit earlier, some people are just "too weak for the truth"

, i.e. tend to give too much credit to the current system in various aspects.
